Tyvm sir, I will echo anything I figure out about those wander modes and attack unknown 3.
In fact here are the (purely observation, not proven via disassembly) notes I got out of testing wander modes for Gato, which I'm sure you've been over, but just in case. The first two columns are not nearly comprehensive.
Wander Mode Value | Monsters that use it | Description |
00 | Just about everything; the null counterattack | Does nothing, no animation, no turn consumed returns to previous mode? |
01 | Yakra after his "drooo" tech | Stationary, walk animation |
02 | Not observed yet | Stationary, walk animation |
03 | Not observed yet | Walk toward target - forever. Never proceeds with its next turn |
04 | Can't recall, but probably bosses | Stationary, but uses a different animation than walking. |
05 | Hench | Stationary, face target, slowly loop a non-walking animation |
06 | Gato | Walk directly away from target. Possibly as far as he can get during his turn, possibly turns around due to obstacle, possibly wants to keep a precise distance |
7 & 8 | Not yet observed | Stationary, walk animation |
0A | RolyRider, Blue Eaglet | Wanders aimlessly within a limited area around the target | 0E | RolyRider, Naga-ette | Walks circles around target keeping the same distance where possible | 0F | Avian Chaos, Blue-Eaglet after counterattack | Seems to be either avoiding all PCs or seeking corners |
Obviously this is not a complete list, but I hope it helps. |
