Monster Junkie
Although they didn't completely break my game, these have all put serious strains on my abilities to challenge the players...
- Fortification property for armor...this stuff effectively eliminates critical hits and sneak attacks from the game at a relatively cheap price at mid- to high-levels. I had to house rule heavy fortification to 75%, moderate to 50% and light to 25%.
- Enlarge person. This is brutal at low levels when used by warrior-types with a level of sorcerer. And it bugs me to no end that only enlarge person exists, not enlarge monster to level the playing field. In my next campaign, I'll probably replace the spell with the expansion power from the XPH.
- Mantle of Egregious Might. This spell from the Book of Eldritch Might has made the party's wizard-type's spell DCs nigh-unbeatable. Combine that with the greater magical flow enhancement spell from the same book, and it is deadly. I really like the BOEM spells, but I'd have to seriously consider allowing many of them without alteration in a new campaign.
