Ground Bash
Upgrading this to its maximum level will grant you:
+66% skill damage to this skill
+20 power to your base stats
About: This increases overall power and make Ground Bash hit like Glaive Strike. This is a very useful skill because its so quick and it also unlocks at level 66, making it the very first one we can unlock.
Shining Crescent
There are three options:
1. Spirit of Iron: Reduces damage taken by 50% while casting. Successful hit against a monster decreases target's endurance by 4.5%. Stacks twice for total of 9%. (Solo)
2. Velocity: Increases casting speed by 15%. Grants additional Ragnarok Point recovery by 25 points per hit. (PvE)
3. Bleeding: Successful hit against an enemy player applies a bleeding effect, which reduces target's HP over time and increases damage taken by 9%. (PvP)
You should take the Velocity spec as it decreases animation time by 15% total and gives an extra 50 Ragnarok points per hit.
Maelstrom
Upgrading this to its maximum level will grant you:
+33% skill damage to this skill
+40 crit factor to your base stats
About: This increases base crit factor which will enable us to run even less crit factor on our gear and maintain ideal crit rates.
Titansbane
There are three options:
1. Focus: Increases damage of Titansbane by 30%. Generates 200 Ragnarok Points per hit. Generates 400 Ragnarok Points on successful second cast. Allies no longer receive Arun's Wail or Shara's Scream effects.
2. Sheen: Doubles skill damage bonus of Arun's Wail and Shara's Scream effects but decreases damage of Titansbane by 80%.
3. Armor: Resists Knockdown and Stagger while casting. Additionally, Arun's Wail reduces damage by 10% and Shara's Scream reduces damage by 15%.
You should use the Focus spec as it gives a full Ragnarok Guage.
Gungnir's Bite
Upgrading this to its maximum level will grant you:
+100% skill damage on a 35% chance
+20 endurance to your base stats
About: Due to the sheer amount of times we use this skill, it isn't hard to see that this will passively increase our damage a fair bit.
