Guild points

1. Each completed task adds its category's base points to its skill's guild; a task that stops being complete takes them back.
2. A skill's total points are the base points of every task it lists. A rank is reached at ceil(total × the rank's point percent) points.

Prayer XP

1. While any prayer is active, each of your hits that deals damage pays XP from Base experience, with that hit's damage and the summed base cost of the active prayers.

Cutting a tree

1. A tree takes Max health damage to fell; each hit lands after Interval.
2. Every hit rolls each On hit item chances entry, doubled with Output Doubling Chance.
3. A hit deals 1 damage. While the tree has more than 1 health, Instant Cut Chance fells it at once; otherwise Weak Spot Chance makes the hit deal 3 + trunc(0.1 × Max health), and Double Damage Chance doubles the damage.
4. After the damage, each overgrowth effect of the tree applies with its Application chance to every unlocked tree of the effect's category.
5. A felled tree rolls each On cut item chances entry, pays Product quantity doubled with Output Doubling Chance and XP, and returns to full health.
