Chests
Chests are a rare item drop from Skills and Combat.
Chests can be randomly found doing most tasks in the game, whether online or offline. The exact chance of finding chests greatly varies, but the higher level tasks you complete, the higher chance at finding a chest. Additionally Monsters are known to hoard chests, making combat a great and predictable way to farm chests.
Chest Drop Rates
When it comes to obtaining chests through Skills, the drop rate is a function dependent upon two variables - the base chance of a chest type to drop, and the level requirement of the current task. The base drop chances are as follows:
Common treasure chest: 0.015%
Rare treasure chest: 0.003%
Exceptional treasure chest: 0.0005%
The function to calculate the final chest drop rate is:
Chest Drop Chance = Base Chance * ((Task Level Requirement / 10) * 1.033)
Example: To calculate the odds of obtaining a common treasure chest from foraging 
Seaweed:
0.00015 * ((90 / 10) * 1.033) = 0.00139 = 0.139%
In other words, every task action of foraging seaweed has a 0.139% chance to obtain a Common treasure chest.
Tip: Wearing 
Treasure hunter gloves when skilling 
Agility boosts the chest drop chance by 50% making it one of the best ways to obtain chests in the game.

Clan Credit Rewards
Clan credits are received for opening treasure chests. Players with 
Premium membership status will receive 25% more credits (rounded down).
Note: The clan credits received from opening chests appears to be calculated based on the number of chests you open at one time. Due to the way clan credits are rounded, this means that in some cases if you have premium status you can receive more clan credits from opening multiple chests at a time. (i.e. opening 1 exceptional chest provides 12 credits, but opening 2 exceptional chests at once provides 25 credits ((10 * 1.25) * 2 = 25) instead of the expected 24 credits.
