Need Pro Zerker help

Ok, So My Current stats are

40 Attack
55 Str
40 Def
40 range
31 Pray
40 Mage

(Only started working on it a few days ago)

So what Levels should I get?

Also if your Super smart at Maths help me work this out.

There is about 20k from 40 - 45 Def.

Quests I have done.

Dragon Slayer
Nature Spirit

What other Quests do I need to do (RFD Quests aswell) And what Amount of Xp will it give me?

 

Honestly, look up a turmoil zerker guide. Your defence might already be to high..

edit: I would go by this
https://www.mm-rs.org/forums/topic/65852-guide-to-turmoil-rune-pure/

 

from 45 defense after doing Turmoil Quests i got 47. So you might be still ok. Just go for 75 99 45 tbh. Solid stats not too much of a high cb.
