Yes, it's a Wizardwars 1.2.7
It's not the latest version though, because there is a version newer than it (1.3.0), however :
1. In 1.3.0, you have to edit listenserver.cfg inside the Wizardwars folder to make Thornplant usable in deathmatch mode (not just CTF mode). In 1.2.7, you don't need to do such a thing.
2. In 1.3.0, BOT are good at spamming satchel, but almost never used their staff for melee combat. This is sometimes give them disadvantage because some classes like Geomancer or Frostmage are great when attacking with their staff.
3. In 1.3.0, BOT never play as Dragoner and Sylvanist. Therefore, the only way to fight them is against human player.
Now back to the topic. If you know anything about BOT's unique power, please tell me. I'm just afraid if attack type dealt by the BOT is something like "Direct HP Removal" instead of "Physical Damage". And don't forget about magic missile above
