i would love to use channel more, sadly they are running our fast: )
especially as we play long fights - little rest adventures.
our DM allow resting, but when we rest and re group - so is the enemy...
so - scroll burning after fights is the best healing we got. channeling is supreme - but limited uses.
BTW - my azata companion, has int of 14, wis of 17 and cha of 20. with my ranks she is a beckon of diplomacy and perform. she scout, detect evil and magic, perform for crowds while i gather information and understand all spoken tongues.
in combat she is either the spell runner - fly in, deliver - fly out.
or my "quicken" free feat. i summon and buff the party while she buff me.
when the main fighter is almost dead - i push him a side - all buffed up and take his place.
also - commune spells are amazing on scrolls - when 2 are cast same round.
i only wish i also had room for spring attacks,
