So after getting mauled by T3 ice jellies, I came up with this.
A new style of bomb, obtainable with 20 bark modules to start at 3*.
Basically, it would have the charge time and radius of irontech destroyer. But when it detonates, jelly spikes (like those from T3 jellies) randomly appear over a period of 3 seconda in the radius of the bomb. It would basically be like a spikepit bomb, but with spikes randomly appearing and disappearing (better yet, make the spikes like those in GiTM boss).
Bomb is like this at 5*, with baby versions at 4 and 3*, acquirable with bark mods. Spikes and radius increase in size as level up. Damage would be: Probably 120 neutral e28 dmg per spike.
How big are these spikes?
