i decided to test it tonight, found some mountain orcs around tilverton
the size of the "patrol" (very small, last time i ran into any they were in a group of 5 mountain orcs, but i wonder if the tigers counted as part of the patrol? or was it a double spawn?)
2 Mountain orc scrimshander
1 Mountain Orc Scavenger
2 Tigers
this was i am guessing not the average size of a patrol in the mountains, they used generous amounts of healing (which really makes sense). the left my two fully buffed level V fire summons as "badly injured" but the orcs and tigers were eventually defeated (i rank their fighting ability in the game as formidable, EDITED they are slightly above that of a hullack hill giant individually in difficulty to defeat, in larger numbers they could pose a problem to the ill prepared or the over confident, there were no spell casters or ones who used a fear thing among the group i encountered)
they dropped 100% for the mountain orcs(i cannot see people getting rich off of the mountain orc heads, as they require a bit of effort and resources to defeat)
and the tigers dropped the normal meat, bone, the tigers did not drop a hide
