Yikes..If you want to pay a ton for the 150 one go ahead. Ik on epona 130 tridents go for about 200k.
150 is the req for the best aggy trident..Wyrm is 140, and ancient Wyrm is 160... Idk where u got 150 from.You said your 135 wyrm is 25 lvls away. What server are you on?
Imo try the spear build on your 135 ranger first because your lvl 35 won't be able to max many skills therefore dps will be a little dull.
Apologies for all the questions but you guys are helping a lot..

Okay err.. (Regular) Wyrmbone or 110 aggy trident?
And.. Wyrmbone or 130 aggy trident?
(Which of these are better)
