Me and a friend of mine have been playing TQ: IT together for a couple of days. We just have beaten normal. I am level 42, and my friend is 44.
Act I and Act II weren't hard. But we began dying in Act III. And Act IV was just unfair. The monsters were absurdly strong especially towards the end, we didn't stand a chance. In fact, the Blue Gigante just before Hades killed us more than ten times (single shot). We couldn't kill him, so we had to run past. We were like put into Legendary without warning.
I was following the guide for compendium for Oracle. Everything seemed great until a single crab killed me easily in Act IV. I was like what the hell. Things weren't much better for my friend who is a conqueror. He followed a very nice guide to build his character. I am using a staff and lightly equipped, have high energy regeneration. My friend is heavily equipped and has high health regeneration.
I have Ternion-tree and Storm Nimbus-tree all maxed. Put 2 points in Storm Wisp and maxed Eye of the Storm. 1 point in Liche King because I knew he was useless on normal as opposed to what the guide states. I will invest points to his tree on epic. Lastly, I use squall and it's synergy.
My death count? It is 110. It was just 50 at the beginning of Act IV. I don't think I'm a bad player. I have played this game a lot 2 years ago. And here I wonder why a lot of people are talking like "I am in legendary and just died 2 times including normal and epic", "Oracle is great I am soloing Typhoon." Maybe this applies for single player, but definitely not in multiplayer.
I know that the difficulty increases in multiplayer with each additional player. But I'm worried about epic and legendary. My staff isn't great. So I do 450 damage with Storm Nimbus activated. I couldn't find a better one. We were to every part of the world and even ran Typhoon several times but no luck.
