today task was Death Splinter, it took a while to complete it yesterday so I changed it, I got Life Splinter. The main bruiser I use was ShieldBearer you like would survive long but since he was taunt all attack go to him and he doesn't survive long.
The different strategy I use to get this daily task done was
I used General Sloan to get +1 attack on range attack
I used Mother Khala to get +1 health on all characters
I used Baby Unicorn to increase +1 all Health
I rented Divine Healer to heal
I think this is the best strategy is to rent Divine healer and use Mother Khala for the +1 health, the General Sloan to get +1 attack is nice however the range attack characters are around 5 mana so you generally only be able to fit one or two them in your squad based on the mana limit.
Also noted that Life Characters have low speed so they tend to miss a lot against higher speed
my daily prize was Alchemy Potion
