I was interested to see the character sheets.
Wow. Dude, you REALLY don't see what you're doing here? I didn't get past the first character's magic items. The character has five permanent magic items including what can only be described as an artifact+++ type item (the whip) which has the combined powers (in ONE magic item) of:
- +3 weapons (very rare)
- dancing (very rare - requires attunement)
- defender (legendary requires attunement) Do you let this character get the +3 weapon bonus to AC when he casts a spell? If yes, go read Defender weapon again.
- ring of spell turning (legendary - requires attunement)
- ring of protection (rare - requires attunment) (double the protection bonus when blade singing)
- wand of warmage +3 (very rare - requires attunement) (ignores half cover with spell attacks)
- (extends spell ranges by five feet including touch spells)
- (absorbs 5 extra hp when using song of defense)
Seriously? You don't see that this amount of magic is going to monstrously increase this character's power? At a minimum the character is +3 to hit and damage on every attack roll it makes above the default expectation. +3 is a freaking TON! The character also has +1 (most of the time +2) to all of his defenses. Again, that's freaking HUGE.
Reminder: a PC can only be attuned to 3 items. You've given this character FIVE attuned items (and some extra gravy) in ONE item. C'mon, man!
This campaign is not a great example of the problem. Though I did think two to three times deadly would at least provide a medium to hard type of challenge. I built it to be very epic. I'm experimenting with encounter building for PCs of this power level. So far I haven't found a sweet spot yet for challenging them.
I wanted to build very powerful demon lords. I needed the PCs to be very powerful to fight them. They have their first demon lord coming up. We'll see how that fight goes. I've built that one to drain resources prior to fighting the demon lord.
So you think two to three times deadly is insufficient for the equivalent of a medium to hard encounter against PCs with this level of power. I'm going to have to do some more experimenting.
