Hey let me give you some tips on ToC.

1. First fight if I do not like the combo I get IE Healer, Rogue, War etc just zone out make someone else the party leader and zone back in. This will reset the fight. Just start with one person inside and the herald will only announce one person shaving time off of the begining.

2. The confessor. I use grounding totemx3 for this fight and part of my /click sequence drops fresh grounders as soon as the timer is up. With the grounders eating up her nukes she is a breeze.

3. The memory she summons. I use a /cleartarget /assist <toon> /use Dark Jade Focusing Lens to recover my guys from the fear bomb.

4. Purge off the renew on the memory.

The Black Knight is a whole chapter onto himself there a bunch of threads here on how to beat him.
