Suggesting mod features (only if possible since the game runs on a server):
1. Ad reward given that skips the whole ad but still give rewards.
2. HP, DMG, and diamonds multiplier (No unlimited diamonds as it defeats the purpose of the grind of the game, but with multiplier, players can have the choice).
3. Always win battle (even if lost, game still thinks you won)
4. Immortality
5. Unlimited skill usage
6. Equipment dupli (press one item and game thinks it's multiple (e.g. you get a sword with bash lv.1 and system thinks you got 3 or more depending on your choice)
