Ok i have 3 question here:

1st: Blood Presence - Ongoing: If your hero would deal damage, it deals that much +1 instead.
When your hero deals damage, it heals 1 damage from itself.

 

What happen if i have Blood Presence and i attach Plague Strike to opponent, do opponent target ally - 2 hp for each Plague Strike since i can do 1 more dmg?This is the description for Plague Strike

Plague Strike - Attach to target hero.
Ongoing: At the start of your turn, your hero deals 1 shadow damage to attached hero.
When damage is dealt this way, target ally in attached hero's party has -1 health this turn.

 

2nd: Frost Presence - Ongoing: Opposing cards and effects must target your hero if able.
Your hero has +10 health and is a protector.

What happen if opponent play cards like Frost Nova? Do all my ally still eat the 1dmg or only i will eat?

 

3rd: Death Grip - Ongoing: This turn, target opposing hero or ally must attack if able and can attack only your hero if able.

If i exhaust Death Grip, can opponent target ally choose to in respond uses the ally power? Like Water Elemental? Thx:)

 

1st: No, target ally will have only -1 health no matter how many damage you do.
Plague Strike doesn't say -1 health for each damage dealt.

2nd: Forst Nova doesn't target. It does 1 damage to your hero and to every ally in your party.
So Frost Presence don't affect Frost Nova.
For a card to target, it must contain the word target.

3rd: When you use the power on Death Grip, in response the opponent can use the power on Water Elemental.
The power on Water Elemental will resolve first doing 1 damage to everybody in your party and when Death Grip effect resolves, Water Elemental can't attack because it's already exhausted.

Even after Death Grip resolves the opponent can use the Water Elemental's activated power at any time thus rendering it unable to attack. Death Grip states they must attack if 'able' it does not state they cannot use their powers, effects, or activated powers.
