Hit: how random is random?

[shadedwonder]

Before I mention this: I'll still enjoy the server just as much but there's something I've been wondering about for a while now.

I noticed that when my character's Armor Class is such that a monster would need to roll a 19 or 20 in order to land a blow, they somehow get more frequent critical hits. I've ran into situations where monsters have put together strings of critical hits, sometimes 3 or 4.

That being said... are the enemy's hit dice for attacks 100% random?

The nwn2 game engine has rigged dice.

Jokes aside, it is random. But when you're a player and rely on your AC, sometimes it feels like they're rolling 19s and 20s constantly.

It actually is rigged as of latest patch.

NPCs roll 20s more often. PCs roll 1s more often. Nothing can be done.
