First of all , I go with all the life points full and without lust, I throw the reptile lure potion (until they are 6) holding the attacks and when I run out of potions, I make two attacks and die or lose. I must emphasize that many of the images of the monsters I do not see, only some appear in others a shadow is seen and those that happen to me so much with examples the lizarman warrior, raptor, hornet and big rat & ones more, they simply can't be seen. It will be because I use the Android version ?
Aha, I think that's the problem - you need to then win the encounter after you use the lures. Attack (or Tease) until one more use will win you the battle, use five lures, then Attack (or Tease) to win the battle.
The enemies not having pictures yet is intentional - Hyao is slowly adding them as Zoroj and Gavel work on them. So the pictures you're missing are pictures everyone is missing right now.
