Wow, I hadn't thought of combing these together to make special attacks, that definitely sounds awesome!
Having drawbacks to some of these like "Steel Skin could similarly reduce the range of the tentacle attack" which then boosted something else "but make you steal some armour from the enemy". This could allow for loads of variation so the skills don't really need to be original anymore. Great idea man.

I do think having the ability to storm around as a bull with no cooldown is a bit op, like, every copied skill is sort of a more buffed version of an already existing one. This new Flight skill did remind me a lot of "Tactical Retreat" and I have no problem with "Skin Graft" atm. I think with these new polymorph abilities, the devs were trying to add a lot more mobility to the game by sneaking invisibly, dashing around with no cooldowns (which also sets bleeding) and flying around cause you can. I mean what's even the point of "Favourable Wind" (not that anyone used it anyway) or "Teleportation" anymore.

I don't think too many combinations can be done cause the skills don't last anymore than 2 - 3 rounds. This is why these combinations can be so important so if you activate them in the right order, they can do more damage in general or maybe more physical/magical damage etc... e.g. Using flight and Steel Skin could make it so you fly shorter distances but when you land, you deal some physical damage OR use tentacle lash after having activate Bull Horns will make you drag the enemy towards you (maybe not the whole way).

I will add some of these once we get some really good fleshed out ideas. Thanks for commenting tho laugh
