Welcome to Goldceo.There is a 2Moons guide about summoner tank Build .if you are interested in it .just look through.Hopefully the article can help you. I believe you will learn something from it.
1st off best offense is defense.
the pet u choose is all preference.
I chose libido because tarantuala does poison dmg. Which makes lvling fast in the beginning for staffs because the poison stacks.
your build should go 3/2 spirit/health and every 6th lvl 3 strength 1 health and 1 spirit . If you follow this pattern then when you reach the lvl for your next staff which is every six u will be able to weild it.
(Skill tree) my opinion. I like every skill except for summon blades. my suggestion max them except blades and twin slash. ( you can max summon blades l8r when u have extra sp to add for those people who have resistance to poison.
Skin of forgotten realm is very good skill dont listen to the rumors. If you are a pvper its usefull. The skill doesn"t last long but how long do most pvp battles last? your answer Not very long. It adds alot of defense. I have it at lvl 3 right now and it adds like 50 defense not sure exact numbers.
thorns and evolt max them out right away. low mana cost for pve so grinding is good when lvling. also good for pvp but later on that. summon of bats is good for healing and aoe before u get summon of ghosts. good also in pvp my opinion. usually hits enemy 3-4 times and dmg is reasonable. Not a bad skill.
Use poison accesories or magic dmg accessories thats it. forget fire and other elements you're a summoner not a mage.
(only use element stuff to kill bosses)
Grinding- There is no fast way of lvling except for lvling. 5-12 lvl in noob maze
12-34 castor
34-50 nunvince dungeon requies beach
50-60 castor floor 2- when you reach lvl 52 you get summoner of ghost. aggro mobs to gather your mobs around you and use summoner of ghost and bats. when doing this u will be aoeing and healing. faster experience.
60-crespo ( dungeon )although you can go here at 55
pvp-staff can be very good at pvp.
summoners-worthless fights-if higher lvls u will probably lose if they built right-lower lvls you will win
