Splice DUNGEON DOOR and DEATH SPIKES to make PORTCULLIS. Category: doors. It takes 0d 01h 16m 16s to grow PORTCULLIS from seed to tree. You get experiance points for breaking PORTCULLIS. Hitting it will break it but you need to count the hits yourself. You get at least 1 seed back (maybe more!) from splicing PORTCULLIS. Will you strike it rich? You just have to count the gems yourself. Will you get enough blocks to build something? You just have to find out yourself.
