There is a chance to remove the curse effect as well. If the weapon is cursed, the curse will be weakened, allowing the weapon to be unequipped.The strength requirement decreases by 1 at levels +1, +3, +6, +10, +15 and +21.For example, the spear (a tier-2 weapon with tier-3 scaling (+1/+4)) at +0 will deal 2–20 damage, but at +1 it will attack for 3–24.The damage increases, typically by +1/+(tier+1), meaning that it will gain 1 minimum and some maximum damage to the damage range.
When a scroll of upgrade is used on a weapon, the following will happen: Weapons can no longer have negative levels.As Shattered PD was forked from the original before the introduction of durability, the system has not been implemented, and weapons never degrade in quality.Similarly to armor, the strength requirement is no longer lowered by 1 point for each scroll of upgrade spent.Randomly spawned weapons now have a set 30% chance to be cursed.tier-5 weapons scale by +1/+6 instead of +1/+5, some weapons have different scaling All tiers gain 1 additional scaling e.g.Damage is computed the same way as in vanilla. Weapons can be identified either by a scroll of identify, Well of Awareness, or by getting familiar enough with it by gaining enough EXP while using it. If a weapon is too heavy, its strength requirement can be brought down using scrolls of upgrade. Equipping too light a weapon may mean you won't be able to deal enough damage to enemies in later stages, while too heavy weapons will cause the hero to suffer massive combat penalties. Try to make sure you equip weapons that are at your strength level. Weapons are an essential part of Pixel Dungeon without one, you will become easy prey for even the weakest of monsters you encounter.
