So lets say I put a caster in an aqueous orb. For this caster to cast a spell is the DC of all the conditions added?
Continuous damage while casting
Extremely violent motion while casting
Entangled while casting
45+DC check?
A good question with no RAW answer from my side.
I see three possible solutions:
1) One check for every active condition (the RAWest way in my opinion)
2) One check with the highest DC from all active conditions (rule on my table)
3) One check with the highest DC with an additional +2 (or +X) on the DC for all other active conditions. (the most realistic solution)
