This week's GO is easier than I expected. I'm not strong enough to stun Cthugha quickly, so I thought her raging OD will wipe me. Her trigger is so easy to abuse though. All I needed to do was save a red ability, cast it during raging OD, and she casts her trigger ability instead of raging OD (still hurts, but hurts a lot less.) Also, casting multiple red abilities in a single turn doesn't seem to make her trigger stronger (unlike Saint Nick and upcoming Barong, where they punish you severely for any active debuffs.)

So cast all red debuffs in one turn, eat the trigger. Save one red ability and cast during raging OD. After stunned, she's not that scary. I might actually have a shot at 20 mission points this time round even though I am not using a water team!
