Summon Oily Blob trivia & strategies

  • As of definitive edition, the blob has the skills Fossil Strike and Turn To Oil
  • The Oily Blob is very frail, and enemies will often target it to get rid of it quickly. It has no armor so it will be CC'd very easily. This makes it decent for drawing aggro while also dealing some damage, but there's always the chance that enemies will not care about it at all. A rather poor summoning skill compared to others, but it does have its uses.

      I know is says it scales with strength, but could this skill replace Fossil strike for geomancers (int geomancers)? it has similar geo scalling (75% for blob and 80% for fossil) but has a larger AOE and would give you a free summon. They both leave an oil surface.
      Basically is the loss of Int scalling worth gaining a summon and having the aoe a bit larger?

        Most people says this sucks, so i build my summoner around this. Running an all magic team, so summoner got max summon, max geo and max strenght, with the benefit of carrying capacity and armor distribution. So if there are grouped enemies, a fire surface or somebody is weak to earth, i toss this blob onto them. Hit a bit weaker than a fossil strike, then 2 hits on his own and enemies usually target the blob more than the do target my incarnate. All for 2 ap...but i run ambidextrous, so scrolls cost 1ap. Also strenght sinergizaes with flail skin medusa head (plus geo). Sure, this may not be the best, but is fun if you want to use the blob

          The oil blob itself leaves a trail of oil wherever it moves, and deals a decent amount of pure earth damage with its attacks.

            "Damage is based on your level and receives bonus from Strength."
            Character strength (str scaling) or the blob's strength (summoning scaling)?
