Norebo's Gamble

I came up with this house rule for a player's character, half-orc fighter/cleric, to add some flavor to the class.

Clerics of Norebo can call their deity's favor once a day. All results are valid for the round the call is made.

Roll 2d8.

2. Gambler automatically hits his next attack or makes the next saving throw.

3. One enemy gets a -3 to his next attack or saving throw.

4. Gambler gets a +2 to his next attack or save.

5. One enemy gets a -1 to his next attack or saving throw.

6. Gambler does maximum damage on his next attack.

7. Nothing happens. Lose 50 gp/level.

8-10. Nothing happens. Lose 100 gp/level.

11. Nothing happens. Lose 50 gp/level.

12. One enemy does minimum damage on his next attack.

13. Gambler gets a +1 to his next attack or saving throw.

14. One enemy gets a -2 to his next attack or saving throw.

15. Gambler gets a +3 to his next attack or saving throw.

16. One enemy automatically misses his next attack or saving throw.
