I searched the forums but couldn't really find anything that pertained to this exact scenario. first off i try to stick to an unwritten rule to only use vital strike if a creature is intelligent OR if it's been reduced to 25%/ on it's last term.
I read about spell effects and VS or giving VS to creatures such as t-rex but this is a little different.
Creature in question is a spectre. upping to a 11cr enounter with 4 levels of savage warrior. it has improved natural attack and i'm debating on giving it VS, is this legal? it's not a spell so seems permissible. the thing will be going up against 4 10lv pcs so i'm not worried about 4d6+ 2 levels of energy drain killing them off, just want to know if it's within the rules...
i try not to bend the rules, i prefer to work within them. As a GM i have one nice thing in my favor-templates. i could really bring the pain if i simply wanted to do so and still be within the rules per se, although we all well know micro managed monsters is not exactly how the templates were meant to be used and the CR quickly falls apart ;)
