English Battle Summoner skill trees:
http://rappelz.spartancommand.net/uploa ... nglish.jpgThe path you want to take as a Battle Summoner really depends on what pet you have, what weapon you use and which do you prefer - your charrie or your pet.
If you prefer to make yourself stronger rather than your pet. Go with the far left root - Summoner Weapon Mastery Maxed, Avoidance Expert Maxed, Charge Stab Lv6, Dirk Tornado Lv1-8, Dark Strike Lv11, Concentration Maxed, Deep Evasion Maxed, Double Impact Maxed and Might of the Underworld Maxed.
It would be nice to at least have Lv1 Nightmare in your arsenal just for some help in crowd control in DP's.
Some of the skills I would recommend..
Creature Mastery - Lv20 = 130% stat effectiveness. At least Lv11 to level up your other pet skills.
Creature Breeding - Lv10 = This passive skill also increases how much exp your pet gains when it is formed and unsummoned. Lv10 = 10% exp. When summoned, pets gain 150% exp with Lv10 breeding..
Dual Summoning Lv7-10 = Very useful, and raises your damage output by 1 more character/pet. With Lv7, you can hold 2 pets out constantly.
Power Support Lv20 = Useful if your pets are melee. Lv20 = +100 P.atk, +600 HP.
Spirit Support or Magic Support = Useful if your pets are magic-based. Just remember that Spirit Support (+M.atk/MP) takes almost 3 times more MP than Power support.
Creature MP Extract - If you're running low on MP, and your pet's don't use MP. You can use this to regain your MP. Lv5 = 200 MP every 30 seconds. Lv10 = 400 MP every 30 seconds. Its very good if you're using high MP costing spells like Dirk Tornado or Bloody Arrow.
Creatuer Soul Transfer - If you don't use your MP much, you can heal any other pet's MP with this, by sacrificing your own. Useful if there are Blue Pixies in a DP.
Blood Aura/ Aura of Halisha - Your Jlvl 40 Party pet buffs. Blood Aura is a party Power Support, and Aura of Halisha raises all pet's stats. I heard at Lv3 it is +30 to each stat and +6 Luck.
Life Leech/ Creature HP Extract - Easy way to heal yourself.
