I think it would be awesome if we could make a gambling chest that gives you xp. One gives you only skill xp and one gives you combat xp (prayer is included)
EXAMPLE:
Skilling chest:
Chest 1: 1m per gamble: Low xp amount (100k xp max)
Chest 2: 5m per gamble: Medium xp amount (300k xp max)
Chest 3: 15m per gamble: High xp amount (500k xp max)
The same goes for the combat chest
I would also like to suggest a theiving chest where it gives you items such as a whip (rare), phats (rare) , zammy armour (common), 3rd age (rare), and much more (also gives you 200k per a click)
