Quicky Guide
the most import Boost that you can get have on Survival Records is the MERCENARY… make sure borrow a Mercenary from friend/community… you can use them unlimited times…
your best 4 characters with best gears and equipments… plus the mercenary… you already have an advantage agains the enemy…
for the battles… always kill the weaker enemies first… get the reward buffs… that can later help you tackle the harder enemies…
for reward buffs… I find Lifesteal as one of the best… makes us self sustaining and less reliant with a healing character… a speed buff is good too… so we get to attack earlier than the en enemies…
Reset… one of the hidden technique for this mode… immediately retry/redo/reset the battle every time we are about to lose or an important strong character dies…
