At level 86 I have level 5 spirit hearts and don't regret having Tibia gold. Do not be fooled by the idea of it being "based on magic attack".Here's what happens when a skill is based on magic attack. It uses your "attack" to judge the damage it will do, and then the monster must have magic defense to block damage.So you do not need INT. THe add-on that this skill can cause an enemy to significantly lose attack speed is nice. A nice skill after all that does decent damage too. Should think about it.Screw Attack! Makes you spin around horizontally like a drill and pound your enemy. As a Hawker you have 5 levels available to you.This skill does high damage AND has the chance to lower the enemy's defense, which is awesome. It costs as much as Spirit Heart and has much more impressive results.This is a great skill to start a fight with a yellow or orange monster, as turning its defense down is a great way to start the battle in your favor. This skill is definitely mandatory.
