The Mana Shot is currently the weakest option, restoring only 15 mana—often not even 25% of a player’s total mana—making it insufficient for most abilities. The Health Shot sits in the middle, but its low healing combined with a long cooldown makes it almost useless in dangerous situations.
The real imbalance comes from the Health Bomb, which deals area damage and restores 100% health and 100% mana, far surpassing what its counterpart gifts offer.
The other friend gifts need significant buffs to make them worthwhile choices. Without improvements, there’s no real incentive to use anything other than the Health Bomb.
Postdata: Add Dungeon Buster shot like an option for gift.
