- Mass invisibility works wonders for fights that start as soon as you enter an area. Improved invisibility on a melee fighter is a gods-send.
- Summon lots of high-level monsters and equip everyone with missile weapons.
- Dire charm any bosses, or mass dominate a whole group of enemies.
It seems that the much tougher monsters can be a benefit, as summoned monsters are also a lot tougher, and charmed enemies are usually better in melee combat than your own party members.
Any other tips? I've managed to survive the outside of the goblin stronghold (it seemed all those drums went off at once!), but I'm dreading having to face Slayer Knights down the line. I just hope they can be charmed.
