TL;DR? No. You don't need a particularly strong computer to run this game.
My laptop runs it fairly well without stuttering. I can get around 30fps I think? Here are the minimum requirements according to the FAQ:
Windows (Vista or later), MacOS (10.9 'Mavericks' or above), or Linux operating system 2GB of RAM A 2GHz Dual-Core processor A graphics card with 256MB VRAM and support for DirectX9.0c/OpenGL2.0 Around 5GB of storage space
Most modern machines should handle LOE just fine-- in fact, most modern smartphones have higher specifications than this.
My laptop has: Windows 10 home 8gb of ram A 2ghz Quad-Core processor I believe my laptop has an APU with 1gb of VRAM? More than 5gbs of storage space
Bascially, so long as you don't try to get a super cheap laptop, it'll probably run just fine.
For the past few days I've been trying to fight mobs but they have one of two responses: 1. they are enraged by my attacks, when I hit them it does nothing, and can kill me in three hits, or 2. They aren't effected by my attacks at all and they don't respond or try to fight back. Please help. I don't know where to post this.
