enrage then onslaught and watch enemy tanks die in 1 turn
haha big hammer go THUD THUD THUD THUD THUD
It's good on dual wield builds. It's the best damage you can do for 4 ap. The fact it has 5 hits makes it scale well with criticals and on hit effects. Magic has all the OP source skills but as a melee it's either this or overpower.
U can get this spellbook at level 9 already by pickpocketing hannag in cloisterwood.
Shines on glass cannon fire battlemage with sparkling wings. If there are mob of enemies for sparks to bounce it deals way more damage than mere %300. Requires a good setup, it's satisfying though. For a 2h warrior it's underwhelming and there are better options.
Im confused, say Im using a two-handed. I use a basic attack, thats 2 AP per swing, I swing again, thats another 2 AP, for a total of= 2 swings 4 AP. With Skin Graft and my two-handed, Im getting FIVE(5) swings for 4 AP. Even if one factors in the 2SP, thats a total of 6 points of resources all combined which would net you only 3 swings if we were dealing straight AP. EXPENSIVE, but I wouldnt say useless. Im using Lohar Hammer and Im like OMG Im breaking fools down!! Thats how I ended up here to see what people thought. Not saying its OP but certainly not useless.
Most broken skill out there. Apotheosis into Encourage, Enrage and a movement skill onto your primary target followed by this skill and you oneshot pretty much everything. I am playing on Classic with a normal char (no lone wolf) 40 Finesse and the spear you get in the dream-realm and I just oneshot Adrahmalik with about 3k damage overkill.
Great for proccing % weapon status. My guy using Lohar's hammer has a pretty good chance of a slammin knockdown.
Most people rag on this skill and laugh in the face of those who swear by it, so I'll try to use math to bring order, like so many before me. The SP isn't that big of a deal if you don't mind spamming Source Vampirism, especially for dedicated strength classes with limited source skills to pick from, but 4 AP is a HUGE deal. The equivalent AP cost is 2 basic normal attacks, assuming you don't have to spend AP running to the enemy or doing any kind of buffs or CC. Two normal attacks are simply 200% damage total, whereas with this skill it's 60%*5 = 300% damage, so you're basically spending 2 SP and 4AP for a mere 100% extra damage. Plus, if you dont have the privilege of standing next to your enemy before combat starts, then you may have to spend AP just to get to the target, meaning you might not even be able to get that oh-so-awesome 100% extra damage, not until next turn anyways. But wait, your team has acted by next turn and some enemies have low physical armor, don't you want to use War Stomp to prevent them from doing whatever bull*****the game cooked up for you? On higher difficulties, 100% extra damage won't be enough to finish off the enemies. Even if your crit damage is at its natural max (10 two-handed, 10 scoundrel for 260% crit damage), then the numbers become 260% per attack, which is 520% for two normal attacks, versus 60%*260%*5=780%, which creates a difference of 260%, which is only achievable during end-game or Lone Wolf playthroughs. Yet, even that isn't enough to outright kill enemies in higher difficulties, and even on classic and below it's basically overkill. Even if your weapon has a chance to knock down or something equivalent, it's still a gamble, and at that point Overpower is ARGUABLY better (2 AP is a good deal, but 3 SP with a condition is asking for your entire source usage though). And a final, admittedly subjective note: If you've been hanging onto this skill in your hotbar "just in case," but you've never used it, just let it go, it's very unlikely that you'll find the right time to use it because there is no right time to use it. Just use something else.
I feel like most people don't actually understand this skill or at least don't take everything into consideration, and the skill actually does 60% damage per strike despite the text saying 50%. For an ex. my level 15 lone wolf character has a crit hit chance of 65% (meaning on average 3 of the 5 hits are crits.) and 10 points in two-handed giving me an added 50% crit. damage in addition to the 200% crit. damage most two-handed weapons already have for a total of 250% damage each crit. hit. Let's do the math. 60% of your damage critting for 250% three times is 900% your normal full damage plus 120% for the other two remaining hits for a total of a whopping 1020%. Also if your weapons have any status effects they have a chance of being activated with each strike dramatically increasing their odds. And of course you can pair onslaught with apothesis, enrage, ect. for more devastating effects. And people say math will never help you after high school, class dismissed.
I looked into the DE code, and it's 60% damage per hit, not 50%.
Seems to be doing 60% dmg x5 not 50% x5.
Only worth it with a good weapon proc like atrophy, knock down and sparkmaster buffed
I just used an elf and was able to one shot Braccus no problem. Just used one white tea leaf and some flesh sacrifice and Adrenalin. Then used a polymorph skill to reset cooldowns and could onslaught twice. Using enrage the second time. Even just the first time left him with a quarter hp.
5 hits for 50% damage for 4 ap AND 2 sp vs just doing 4 normal hits for 100% damage for only 4 ap. you basically do less total damage for more cost just for 1 extra hit that could possibly inflict some debuff to the enemy, what a trash skill lmao.
If this was boosted to a higher number, say 80%, it would be a total of 400% weapon damage, which I think would justify the SP cost.
Overpower is just straight up better since:
-Overpower plus one normal attack is the same damage for 1 less SP
-Only 3 turns CD
-Can destroy additional physical armor
-Can knock people down
-It doesn't require 4 ap at once at melee distance which makes it way less clunky to use
Another skill that needs to be buffed.it's equal to 2sp for half basic attack. Using overpower+crippling blow will do more damage(150%+115% compare to 50%*5) and cost 1 sp less. Maybe they should lower its cost to 3ap or add damage to 65%*5 while the ap cost remains 4 (daggers drawn should be 3ap or 72%*5/4ap and mortal blow 2sp).
For anyone who has done more than one playthrough should understand why this skill is amazing. Many groups of npc's start contact by talking, but the only resolution is combat. So start the fight with enrage+guerrilla (40% sneak dmg) or enrage(free crit dmg), and pow one enemy dead. Like the rest of the people in these comments I agree, the 2 sp and 4 ap is too expensive to use in combat. But think for yourselves guys, use it outside of combat and most fights that you can initiate yourself are ggwp. Just make sure you don't get locked into dialogue with this character or you will lose your initiation.
For why I feel Onslaught is useless, I will say for example's sake that your unmodified Basic Weapon Damage is 50.
Onslaught would do [50/2]x5=125 damage, have a 6 round cooldown, use 2 source points, and take up 2 memory slots.
If you skip Onslaught you save 2 Memory and can spend that on Strength instead.
-For the same 4 action points Onslaught costs you can do 2 basic attacks for [50x1.1]x2=110 total damage (only 12% less than Onslaught).
-All your other weapon attacks and skills now do 10% more damage as well.
-You can equip high Strength Requirement weapons and armour which itself can also boost your damage.
-You have 2 more Source Points to use elsewhere.
-You can carry more loot and lift heavier objects.
Even if you already maxxed out Strength, I still feel these 2 Memory points would be better spent on Constitution or Wits rather than spending them to just get a 20% boost to one attack once every 6 rounds at the cost of 2 Source Points.
Onslaught can be bought from Haran in Driftwood.
Lol dudes, what are you talking about? This skill destroys if you set it up with buffs before the turn you'll actually use it. First the guy with onslaught uses Master of Sparks, Firebrand and cripples the target if you wanna make sure there's a target close, but The Pawn talent can make up for it too. Then next turn, enrage, adrenaline(if you wanna crit every hit) and BAM!
You guys get it wrong. It is not bad if you use it correctly. To start with, warriors don't need much skill points into warfare... so you put a lot more in 2-hand, which gives you crit multiplier. If you ENRAGE before you do this, you at least get 2 full extra attack. (Saying 5 X 0.5 becomes 5 X 1, so you get 2 FREE attacks, since you spend 6AP with enrage and onslaught.) And that's not even counting the crit multiplier... which gives you another extra attack per 20 % crit multiplier.
but you got nothing reeally to spend your SP on as a warrior
No clue what they were thinking.
2 SP for 50% damage bonus on 1 attack?
(1 Attack 2 AP 100% damage / 2 Attacks 4 AP 200% damage)
(So it's literally 50% of 1 attack for 2 SP. . . and you can't even choose different targets.)
Useless skill. Five time 0.5x damage is merely 2.5x damage. Cost 2 SP and 4 AP. What a joke
