      Maybe the damage bonus of Geo spells should change according to equipped weapons(strength when using a sword, finess when using daggers). The reasons are, One, the status effects like crippled and knockdown are resisted by physical armor, an intelligence-based geo mage deals earth/poison damage resisted by magic armor, which means unless you have a companion who deals physical damage your enemy will never suffer these debuff. Two, the posion damage is quite low if you don't put any points in intelligence, meaning you have to put points both in intelligence and geo skills if you want to heal your undead character, unlike normal healer who only need hydro skills and no intelligence when healing non-undead.

        Does Companion Tiger considered as Geomancer skill ? If so , this page is missing it. I found it at Huwbert's secret chamber...

          I dont have to remind not to focus on poison skills because of so many enemies with high resistance to it, besides the undead you often come across. Earth is good though.

            Nope, it is correct. It deals Earth damage, but crippled checks for physical armor. So, someone with physical armor will never be crippled by using this skill, since it does not reduce the physical armor (magic [earth] damage after all)

              Some of the spells seem to work differently from the description of the spell. Impalememt: says Resisted by Physical Armour but actually deals Magical damage.

                Worm tremor doesn't appear to function properly
                Characters can still move with it applied, albeit at a massively reduced pace, and can teleport themselves with movement skills
                For example, a fighter could phonix dive, a rogue could backlash etc
                It seems to block other characters from teleporting them which IS NOT GOOD, since they can still teleport themselves; it means you as a caster lose a major control skill for a movement slow and some ongoing poison damage
                It costs 3 AP too, so it should actually stop them from using teleport attacks given how much AP it costs

                  Reactive Armour has to be updated. 2 AP, 6 CD.

                  2 points in Geo are still a must have on any physical melee character.

                    Cannot Stress enough how useful some of the level 1 skills are in this tree. Fortify alone is a worthwhile skill on almost any character for your early and midgame and dust throw on any character even a non archer can be a life saver. My rogue if you can even call him that anymore (Scoundrel, Necro) even has some gemomancer skills just for the utility.
