The writing quality and update stability are really great, but everything else isn't. First of all, the world design. If the lowest tier orb gives 50 strength or some bs like that, why was the giant's strength a B-rank skill if low tier orbs drop like pinecones from a pine tree? Also, the infinite focus ois total bull shît, and really doesn't work. I would understand if the mc had a ability that multiplies his focus by 10, 100 even, but infinite is too much. The mc went from 1-100 since the first chapter, and there really isn't any character development. The mc is a fücking coward and really dumb. Why would he sell skill books because they wasn't suiting the type of build he was doing? For example, the golem summon spell was just sold without an explantion. He isn't unkillable, and if a speed class rushes him while everything was down, he ded. The golem provides ample protection even when he disables the barrier, and will also stall the boss for him. Why did he use the giants strength skill book and sold the ice spikes? That giant strength book is the one that doesn't match your build, and who tf makes a 'build' in a apocaplyse setting? Wouldn't he keep every spell and orb and item since he is insanely conservative?
