Bro, take spear lunge at lvl 1.
+18% evasion is +18% evasion, it’s a panic button. Better to have it then not considering only swashbuckling is a worthwhile skill otherwise from peltasta.
Why would you make your live harder by passing spear throw 5? If you get more skills later on and dont’ have to spam it / end up not using it, you can always invest a bit of money and reset those skills to make your char better. Pierce isn’t as good as you think, it’s strong yes but synchro thrusting is actually stronger by a lot then pierce is. Problem is, you need a spear and shield to use synchro thrusting, meaning you wouldn’t get a bonus from 2h spear mastery from dragoon
I am a fan of gae bulg personally because of the +15% bonus to all physical incoming damage of mobs hit by it, for 7.5 second. I wouldn’t pass on dragontooth but dragonsoar though.
Again, spear throw lvl 5 makes live so much easier even more with peltasta that it’s a no brainer. Reset later if you feel those points are better spent elsewhere.
Both dragontooth and serpentine are apparently 5 hit skills. Multihits are good for you, even more multihits that are supported by spear lunge which gives +50% pierce damage for 6 seconds. The reason is, there are only a few ways to stop skills from falling off. The ways are - have a +% modifier that increases the skill with your levels, the more modifiers the better. Flat numbers will eventually end, the reason multihits are good is because each hit is affected by your strength making the skill that much stronger. It makes them fall off much slower, in comparison to 1hit skills, even if their damage is tremendous. The only different skills are skills like gae bulg that additionally buff you up. Hence modifiers. You want those.
