Tree Drops OP Items Add-on 26.30+

Every broken tree trunk in Minecraft can now bring a completely unexpected outcome. The mod Tree Drops OP Items replaces the usual wood harvesting with random events: you might get huge supplies of rare items, encounter a dangerous boss, or even end up with a loyal pet.

Each broken block basically becomes a Lucky Block or a Luck Block: you can receive both positive and negative surprises, including traps, Anvils, and Dynamite, so gathering wood requires caution.
