Can not do any damage to Guardian of the Minotaur.

Hi GGG,

I am reporting this because it's a bug or I don’t understand the mechanics of the game.

I ran Maze of the Minotaur Map 20% quality rare corrupted, nothing special, no damage mods etc. Map had Maven presents. I killed all the mobs and got to the Guardian of the Minotaur.
I played lvl92 character named Eakfast using Earthquake + Ancestral Warchief + Vulnerability with six linked Atziri's Disfavour at 30% quality. I like to play this character because it’s very powerful. To my surprise I did not do any damage to Guardian of the Minotaur, zero. I continued the fight for 10 or so minutes and the Guardian of the Minotaur still had 100% of his life.

I still had 5 portals left so I decided that I will try different character. I login with a character named Mario_Cobrettii with Cobra Lash as my main skill. It has legacy claw with 60% chance to deal 100 more damage and three lvl 5 awaken games in the six link. I also replaced Greater Multiple Projectiles with Vicious Projectiles Support. It was less than a second when I joined the area and got one shot and died. I tried again a couple more times, but I could not do any damage to Guardian and kept dying from one shot. After that I quit because I was very frustrated, sad and angry.

Can you please clarify for me why I couldn’t do any damage to the Guardian?

I also have one more question about Atlas. My understanding is that completing Atlas of Worlds will help you with maps drops. I completed 158 of 164 and 108 of 164 and I have 32 Watchstones applied to the Atlas. It shows Awakening Level 8. I ran 5 red rare maps with 20% quality ( I used 4 Cartographer's Chisels on each map and Orb of Alchemy or Orb of Binding ). From those 5 maps I did not get any new maps. I killed all the mobs and the bosses. So, no maps and nothing in return. That is so disappointing. I’m not sure what happened, but last week i was getting plenty of red maps, but now 0. All I did was add 5 more Watchstones to the Atlas so I will have all 32.

I’m confused now, what is the point of completing the Atlas and using Cartographer Chisels on the maps ? I just lost 20 Cartographer Chisels and 5 Orb of Alchemy. All I got was useless rare items sold to the NPC. Also, I don’t understand why character inventory is so small and why portals disappear after you enter the map? I killed the mobs and I got the loot. It’s mine loot, it’s useless loot, but I want to sell it to the NPC, but the inventory is too small and you have only 6 portals, why ? it makes no sense.

BTW, this is in standard league. I don't want to play new leagues anymore. I find them very frustrating.
I played all the leagues until Ultimatum league. I can elaborate more on that later.

Thanks in advance for your time, I hope to hear from you soon.

Cheers
