Any vials that require fish are nonstarters as fish are a significantly limited resource relative to vegetables and meats.
Since fish are critical to craft higher health+ focus food recipes, there’s just no world in which I will use the fish instead for a focus vial or stamina vial that somewhat increase my gain for a little time, when a food that heals 60-70% of my health bar plus gives me 1/3-1/2 of my focus bar can completely turn the tide of a battle.
Then there’s the elemental flasks. Grenades themselves are severely undertuned. 90-135 damage is just pitiful for current mob HP at lv30, it barely scratches more than 1/7 a regular mob’s health bar. For a single use consumable.
To top it off, the elemental flasks consume GEMS. You know, the super, incredibly scarce gems. No way I will ever use up my gems for a 90 damage lightning or cold flask. I’m at 59 hours played and barely have 2-3 of a couple of gems and exactly one of a few others and none of the health%/max focus/lifesteal ones.
