BeaconsPlus2

Beacons Plus is a very powerful plugin. It can give you very powerful effects. Scroll down to read the boring description, but there's a kitten.

BeaconsPlus2 is a very powerful mod. When you place a beacon, right click on it. There are multiple effects you can buy, with multiple tiers. You click the item on the right to upgrade with XP. It cost XP to get the effects but it is very powerful and worthwhile. The more tiers of the beacon you have, the further the range. The maximum range is 256. The beacons also have feather flying, which lets you fly to a certain height within the beacons radius. It is expensive. The top tier is 256 blocks.
