*The Multi Attack Is cap in 4 . but when you play in battle arena . your multi attack divided by 2 . so your multi attack became the total of +2 ? it is possible when i put 4pcs +2multi attack affix , i achieve the cap of multi attack in battle arena ?

Multi attack is capped at +2 in arena. No matter how many multi attacks you put in your gear(which would be like 24 total if all your gear are eternals with +4 multi attack each), the cap will be +2. Please refer to this guide for a more specific set of arena caps.
