Spikes

     This mod adds 5 spike blocks, which damage any living entity or player that walks over the top of it. Each spike increases in damage done per hit relative to their crafting tier, starting at half the damage of a wooden sword and incrementing consistently to being half the damage of a diamond sword hit. The spike blocks deals player damage to non player entities in order to drop xp. The spike blocks are also capable of having mobs spawn on it for easy mob farms in skyblock setttings. 

This mod was created due to a lack of blocks of the same functionality present in 1.10.2 as Extra Utilities spikes are not in the 1.10.2 version currently. This mod was created to fill that need.
