Help me witha few mechanics questions pelase

I got a level 21 ranged attack totem socketed into skin oif the loyal so its a level 22 RAT gem.

Ranged attack totem level: 22
Totem life modifier: 106%

How much hp do my totem got?

Another question: Do all totems have same amount of life? You'd think decoy totem got higher hp then others?

Edit: A third question. Is 0.75 damage done by players to mobs rounded up to 1 or down to 0?

1. A level 22 RAT summons a level 74 totem which has 6444 base life so you just apply a 106% increase to that.

2. Decoy and ancestral totems are tougher, the other ones are supposed to have the same amount of life.

3. It is rounded down to 0.
