So, bearing in mind that I will soon be going up against yuan-ti archers on insane difficulty, what do you all recommend?

Summon near the archers while your fighters take on the front row. My favorite is to get a few summons to join my fighters and then introduce some undead or beetles to the archers in the back row.


I also tend to let my mage focus on them as well--Chromatic Orb (they have good saves though), Confusion, Web, Blind, or Slow. The idea is to DISABLE or DISTRACT the buggers as much as you can.

Clerics cast usual anti-buffs (Prayer/Recitation) as well as throw in the Curse spell to give the Mage better luck on the archers. Mental Domination may do the trick to cut the numbers down one notch as well.

Have the Druid pick on them with their basic Sunscorch (trying to blind them) and Alicorn Lance (giving the summons a chance to get a hit in or two).


Now...as for the High Archer and his flock of arrow twangers...

Take that pure Druid in there and kill them all while invisible [Static Charge.]
Why? I want all those cute +1 and +2 arrows (+2s' for snake BOSS.)

My tactics are basically similar to Roboghost's. Summoning creatures near the enemy archers also bring about an added bonus. The enemy archers will switch to melee and thus you get to loot their enchanted arrows.
