Rune

A little game I thought up last night. In the game Rune, you explore maps with the help of runes, spells you can summon by creating a odd pattern with block. There's finite number of items you can craft spells with, and you can replenish them in dungeons, hidden areas of a map where you can take from the chests to get more materials. You open your inventory and rune-crafting menu with the Q key, and there, you have two halves of the invetory, one which holds materials, and the other holds spells. You make runes like you would craft items in Minecraft.
RUNE IDEAS:
From Valyou
Dungeon Finder - Finds dungeons full of loot for you to take.
Bounce - You can hop up with it.
Potion - Make a glass container with some enchanted powder in it, then walk up to a stream of water and fill it, then it will become a potion that can heal you in need.

Think of some more runes in this thread that would fit a mideval theme, and I'll put them up on the list with you properly credited!
