What kind of enemy you had the hardest ? (The Witcher 3: Wild Hunt)
I have personally Illarikam killed him 3 or 4 times. and Ridin me disappointed at all, at level 35 on the complexity of death killed him using only the thunder and hoping it would be really difficult and epic battleSpoiler
Leecia (killed only when they understand the tactics: there just had to run away from her when she calls their twins)
Emmerich (yet coming from him, just the keyboard broke)
The Ghost of DLTS in the house of Von Averkov (still don't know how to get max complexity: health from paintings to regenerate too quickly not enough time for them to run up)
Ghosts at the lighthouse in ng+ on the last difficulty (that's why it is in ng+ they become imbovane, in a normal game was not)
In the first pass, even on the average level of enemies I was Caranthir and Eredin.
Ordinary monsters did not cause any problems, it's a little vysokonapornye ulguli and utoptsev/wolves in large number of Islands. Armored trolls, elementals, etc. archigraphy cut easily through the shoals and quena. Without quina no room for error, battles can be long, but the tactics of these enemies are rather monotonous.
Do not understand why everyone is writing about the battles Geralt - there is always the opportunity to rebuild the build, to look for better armor, generally to postpone the job for a while - until you swing. But CRIS is much more complicated on higher difficulty levels, her battle with the witch on the 3rd difficulty level very-very difficult to pass. I thought the keyboard would break. My fingers are numb from pressing on the same keys as are killed in several strikes, and unlike the infamous fight with Illarikam (which is normally goes if you to prepare) the witches three, each with its own characteristics.
for me the most difficult battle was against the Ghost of the lighthouse. Or is there a trick to what is needed or build to the signs against him did not roll. It poured for about 10 minutes, then he took it and completely restored its HP! Waaaaaat? Could not resist. The only boss I had to kill through the trainer, alas. The complexity is maximal. By the way this is my fifth playthrough and still nothing happens, only through the trainer.
A large pack of wolves/utoptsev (at first, then got the hang of it) and the nightmare wives Eureka maximum complexity.
Don't know I personally have problems with the bosses was not, unless you count ng+, so there was hard, and so I would not say that it was too hard, I'm at all levels, the complexity of the game mastered.
