In this guide I will be covering how item bonuses and prefixes work with equips in Rusty Hearts. Item bonuses are determined by several factors, including:
Let's use Arcane Chain Mail as an example. As stated in the tooltip, it can have at minimum 2 additional options and at maximum 3 additional options. Here are the possible prefixes and options the Arcane Chain Mail can have:
So, because the Arcane Chain Mail can have 2 - 3 item options, it will select 2 - 3 bonuses at random from this list. Let's say Rusty Hearts chooses HP +%, MP +%, and Critical Power.
Please note that the stats shown in the list above do not follow any sort of easily calcuable formula. It's entirely dependent upon lookup tables.
Rusty Hearts now selects a prefix from the list of chosen bonuses. The prefix it selects is important. The stat associated with the chosen prefix receives a boost. For example, "Hardy Arcane Chain Mail" would have an HP boost of 2.73 - 3.00%, or "Reckless Arcane Chain Mail" would have a Critical Power of 4.78 - 5.74%. The prefixed stat will always have a better bonus than a non-prefixed stat. So, it's important to look at the prefix just as much as the item bonuses if you're looking to maximize a particular stat!
This concludes the tutorial. I hope this clears up any confusion regarding how item options function in Rusty Hearts.
