Lumberjacking
Cuts wood. A character past 98 in both Swordsmanship and Lumberjacking gains a constant axe bonus.
Lumberjacking turns trees into lumber. Carpentry, bowcraft and the fish oven all burn what it produces.
The axe bonus
Fighting with an axe adds to your damage: a quarter of what you hit for, or a fifth on a character with high magery. The bonus does not depend on chance; it applies to every blow.
It asks for two skills at once: Swordsmanship 98 and Lumberjacking 98. Under a total cap of eight hundred, where eight skills can reach mastery, a double requirement is a real investment — you have to be a woodcutting warrior.
On the old shard the bonus accidentally applied to swords rather than axes. Here what opens it is genuinely holding an axe.
