Fields

guid

This references the “creature” table tables unique ID for which the entry is valid.

pool_entry

The identifier of a pool template to which this creature belongs. The value has to match with a pool identifier defined in the “pool_template” table.

chance

The explicit percentage chance that this creature will be spawned.

If the pool spawns just one creature (max_limit = 1 in the respective pool_template), the core selects the creature to be spawned in a two-step process:

First, only the explicitly-chanced (chance > 0) creatures of the pool are rolled. If this roll does not produce any creature, all the creatures without explicit chance (chance = 0) are rolled with equal chance.

If the pool spawns more than one creature, the chance is ignored and all the creatures in the pool are rolled in one step with equal chance.

In case the pool spawns just one creature and all the creatures have a non-zero chance, the sum of the chances for all the creatures must equal to 100, otherwise the pool won’t be spawned.

description

This field usually names the creature corresponding to the guid and mentions which spawn point it is.

Example: RARE Snarlflare (14272) - Spawn 1
