The Trainer is a tool that let you train with slimes, monks, gargoyles or any other training monster.
The HP Training is a feature that allows you to hit creatures till a determinated health porcentage, i.e, while the creature has enough health, the BBot keeps hitting them, otherwise, when the creature is with low health the BBot stops the attacks. Note: the HP Training will not attack monsters that are not on the Trainers List, this way you can bring monsters to train your shielding like Rats or Bugs.
On the Trainers List select the training creature. For example, training with the Monk:
Attack HP: The minimun HP the monster needs to the bot start attacking
Stop HP: The minimun HP that will make the bot stop the attack.
The Slime Training is a feature that allows you to kill creatures that copies itselves. In the most famous case - Slime, but it works for any creature. It works killing everything that is not on the Trainers List, on the Slime case, you can set it to kill the summons of a mother, the mother will be on the Trainers List.
Its very easy, do a small hit on the Slime Mother and then on the BBot Trainer click on the Refresh button (at the bottom of the Trainer tab), then check the Slime Mother on the list and enable the Slime Training checking the option.
