so for most of my tower runs i use this combo
Furnace, Combustion is a must in tower
Dagrund, heals furnace and provides energy
Ekko, grants energy and CRIT UP plus that electric skin helps alot with Furnace FELL THE BURN
Indigo providing more energy and over all a well rounded hero plus her silence is also helpful.
weighing just under 120 metric tonnes
with the force of one thousand pounds of diesel power in her fists
with a whip sword on her right arm
and a prototype V-cannon residing in her left
her heart is strong and powerful so a vent was created to expel that passion in a flaming rage from her center
she fights for justice, and peace.
don't upset her, for the next time she allows you to motorboat her, it may very well end in flames.
