- Invincibility
Health is on the server, how on earth would you become invincible
- Spawn NPC
You can definitely spawn an npc model, but not actually be able to hit it or do anything as the client sends over the npc index which then the server figures out what registered npc has that index and handles the rest of the logic
- Bank anywhere
It's 2016, if a server doesn't check if the player has bank open, they shouldn't even be online
- Instakill
Again, health is handled on server, how would you use a 'cheat-client' to do this
-item spawn,(duping coins)
You can 'spawn' any item while you have the client, up to the server to verify if you actually have the item in your inventory
-no-clipping
Who cares, but top servers actually check clipping flags/data server-side. I know for a fact Runique does
Overall, seems like something that would only work for new servers with low player bases...or near reality
edit: that video reminds me of videos back in 2012...
