Water magic

[Nikelaos]

Prison of sedna can only be used in water can't it?

it's the one that freezes the water around the enemies i think, haven't used that in ages but can be usefull to hold back tramplers (shambler thralls come to mind) apart from that i think SCs and the larger water summons would break out after a few turns quite easily mind you i don't think the extra protection would do much for an SC so it does make one slightly more vulnerable for the time it is trapped in ice.
