How to use Void Larva Figurine

Void Larva Figurine is a decorative figurine. Put it in a Materializer and power it with electricity to create a copy of Void Larva.

Place a Materializer and put Void Larva Figurine into it.
Connect electricity to the Materializer to make the copy appear (one at a time; the next appears after you defeat it).

The copy behaves like the original enemy and has the same stats, but drops no items, so it is used for training combat skills.

Void Larva	Enemy drop	Breaker's Reach	1	0.1%

"Chance" is the chance to get at least one of this item per try (opening one chest, defeating one enemy, one catch). A "guaranteed group" is the group of a chest or boss from which exactly one item always drops; it does not mean this item always drops (the chance of it being picked from that group is shown in small text). Only items that always drop are marked "Guaranteed". Fishing means catches with a fishing rod, separate from enemy and boss drops. Calculated from the game's drop tables (Conf/Loot, 1.3.0.6) the same way the game rolls them.
