Splice LAVA and DEATH SPIKES to make DEVIL HORNS. DEVIL HORNS belongs to consumables category. It takes 0d 00h 16m 39s to grow DEVIL HORNS from seed to tree. Received experience is a mystery. Keep an eye out for the exp counter. Hitting it will break it but you need to count the hits yourself. You get at least 1 seed back (maybe more!) from splicing DEVIL HORNS. Profiting with this might be questionable. Massproducing DEVIL HORNS can be tricky. You will find out after you have harvested a few.
