Calculators
What the calculator counts: the monster's base XP × our rate, with the server's level-difference
rules, at 11 or more levels between you and the monster you get nothing at all, and above
level 84 the XP is cut further if the monster is 3 or more levels stronger.
What it does not count: vitality (full vitality gives up to 3× the XP), champion monsters
(3 % of monsters, 10× XP), party bonus, quest XP and XP buffs. In practice you will be
done sooner than this, take it as an upper bound.
How scrolls behave on failure:
a normal and an improved scroll destroy the item into crystals.
A Blessed scroll keeps the item but drops the enchant to +0.
Ancient and Divine Crystal are safe, on failure nothing happens, you only lose the scroll.
The support stone works only up to +9 and cannot be used with a blessed scroll.
The safe zone (100 % chance) is +3 on weapons and normal armour,
+4 on full-body armour. The cap is +16.
