Whats up with bolts and being “blocked by an attacker?
Bolts have a long range and do a lot of damage. The downside is that they have a long casting time, a 20-second timer, and can be blocked either by a target wielding a shield, or because a target is engaged in melee combat. The latter is cause for much annoyance to runemasters, because the definition of being “engaged in melee combat” doesn’t seem to make sense at all. When you solo, bolts will never be blocked in this manner. But when grouped, a bolt can be blocked by a healer stun spell, a debuff, an archer’s arrow, or…nothing at all. Bolts are also affected by a targets Armor Factor which is shown graphically on this chart.
