Eredar twins are affected by CoT

[Dorakrab]

Both twins are affected by curse of tongues making encounter much easier, but on the other hand you cant see who is targeted by conflagration, making encounter harder so it kinda evens out i guess. Nevertheless both issues require fixing.

Actually, it does not affect the encounter that much - I can tell you because we never used CoT in any of our P1 attempts (each Twin has one cast). However, it is true that no SWP bosses should be affected by CoT.
