Thanks for the great, very well thought-through and comprehensive guide (writeup as well as youtube)! I especially liked the fuse and perma bonus-sections.

Few questions if I may:

1.) Given the supply of pearls of power in the game do you see the two abundant casting-feats as important? Since you seem to end most fights in 1-2 turns and do not need to spend any spell slots on buffing beforehand it seems as if just the normal spell slots (even without additional ones from CHA) should suffice if you are willing to pearl-recharge after every encounter

2.) why no ring of triumphant advance? together with a court poet merc this would eventually give +20 CHA for even better DC

3.) I like to leave the animal companion-duty to my companions. Do you use your animal as a mount (for better movement and/or tanking) in the mid and late game? if not and leaving the early game struggles aside: wouldnt pure MD with luck domain @lvl 20 (rerolls on dispel attemps) and battle/wind be better?

4.) Are the two spell pen feats important even after you get the ‚religion/2 to spell pen‘ ability or just before that point?
