Experience
Monsters range in level from level 1 to level 100. The number of experience points an individual monster has determines its level. Monsters mostly gain experience points through battling other monsters. There may be other ways of gaining experience points as well.
Current implementation of experience points and levelling
When an enemy monster is eliminated, all player monsters that did any amount of damage to it are given an equal portion of (its total experience points / its level) (this is equivalent to giving experience points equal to level ^ 2).
A monster increases in level if its total experience points meet or exceed (its level * its Experience Required Modifier) ^ 3. I believe the Experience Required Modifier is currently hard-coded to 1 for all monsters.
A monster increases as many levels as it is entitled to.
Monsters should not gain experience points once they have reached maximum level (100).
Levelling up occurs immediately; morphing occurs after the battle if the player wins the battle.
Experience multipliers
The experience points a monster gains are adjusted by a multiplier based on the monster's origin:
Captured: x1 Traded: x1.5 Bred: x1.2 Gifted: x1.2 Purchased: x0.9 Rescued: x1.3 Created: x1.0
Sharing experience points
There are ways to share experience:
- XP Transmitter: An item that, if it is in the player’s possession, means that half of the XP goes to monsters that participated and half goes to monsters that did not participate.
- XP Feeder: An item given to a particular monster that means that half of the XP goes to monsters that participated and half goes to that monster (including allowing them to double-dip if they participated)
Experience items
These are out-of-combat consumables that give the monster additional experience points.
Tea gives roughly enough experience points to advance a 4th level monster to halfway through level 5th; Super Tea a 9th level monster to halfway through 10th; Mega Tea a 16th level monster to 17th level; Imperial Tea a 25th level monster to 26th.
