[Dungeons][DM only]My first experience in DFRPG/"I smell a Rat"

[Kromm]

A not-so-secret side to high monster DR in the DFRPG is that it fills a role similar to high HP in other FPRGs: It means the heroes must spend more time killing the monster (as they try repeated low-odds attacks to the eyes, low-damage hits that might luckily roll high, etc.), allowing the monster to take more shots at the delvers. Good active defenses serve the same purpose. A creature could have lots of HP in another game because it's huge (actual HP in the DFRPG), a tank (high DR in the DFRPG), or very capable (high active defenses in the DFRPG). This game distinguishes a bit more.
