Spawning
Use /pvpbot spawn [difficulty] to spawn a bot at your location. Aliases are /bot and /pvpb. Requires op or the pvpbot.admin permission.
Difficulties
All bots wear full diamond armor and carry a diamond sword regardless of difficulty. What changes is their AI behavior:
NPC — stands still, does nothing
Easy — walks straight at you, slow attacks
Medium — strafes, keeps optimal distance, does combo attacks
Pro — aggressive strafing, fast attacks, attempts critical hits by attacking while airborne
GUI
Right-click or shift+left-click a bot to open a 2-row settings menu. The top row lets you switch difficulty on the fly. The bottom row has two toggles:
Auto Totem — keeps a totem of undying in the bot's off-hand at all times
Immortality — gives the bot 2048 HP, full knockback resistance, and permanent Regeneration X
Other commands
/pvpbot remove — removes the nearest bot within 10 blocks
/pvpbot removeall — removes all bots
/pvpbot list — lists all active bots with their difficulty and coordinates
/pvpbot help — shows command list in chat
