Movoda Manual - TunaCasserole

+2 Gem Finding for 30 minutes
Can be made at Cooking Level 33 (Erfdarian)
(Plus tool of type Tinderbox)
Bunch of Cilantro
*Also requires 1 log/lumber to cook.
If you already have gem finding +100 or higher, then eating additional tuna casseroles only increases it by 1.
It has also been said (by mskwik) that the maximum effective gem finding level is +50, so that increasing it beyond that point has no effect.
