Idea 1. There should be a balance spell called "Spell Steal" 3 pips, 60% Accuracy, level (70-80, you decide what you perfer) Gold cost: 9001 in bazaar, anyway, What the spell does is when a monster casts a spell, and you are using the spell on him, if you go first, it will give you the spell whatever the monster casted.
Idea 2. New topic in backpack, "Misc items" You can store new optional items in this section, Look below for some ideas. 2a. Name tags (They rename items in your backpack, w101 dictionary.) 2b. Backpacks, (The give no addional space in your inventory, just appearance) 3b. Portable dyes (You can dye on the go instead of going to the shop) (You decide the prices, :) )
