Couple of points:
- only need to type /ass to end a raid. /ass works to both manually start a raid and end a current active raid.
- Kiting is good advice.
- Wooden shields can help negate damage if you're not great at kiting. They halve the damage you take... just remember to block when the enemy is attacking, then attack back afterwards. These are easy to craft as well.
- Wooden spikes are also easy to craft, plce a bunch of them in the usual paths that raiders come ... and you'll get a start on killing them. Heck, as you said... you can just cheese them over the spikes over and over again to kill them.
- Also, make sure you have equipped any NPC's in your base with a weapon, and hang around them. Even if it's just the male and female MC's, it can help deal with the raid.
- If you're playing as Yona and get targeted... and not confident of your kiting skills or ability to finish off the raid, switch to the male MC (either talk to and select switch, or type /switch in the enter-box). This will prevent Yona from being raped if she gets downed by the enemies (at least till the Dev maybe changes this).
- If your playing as the male MC, there is no loss from losing to a raid... at least not in the early stages. All you'll lose is the time you wasted in fighting them and then re-spawn. When you re-spawn the raid will be finished and the alive raiders will have left. Still, if you do manage to kill any of the raiders... you can go loot their bodies after re-spawning.
- Male MC can be raped ... and the enemies that do this come in raids, but that's usually much later in the game. You'll need to have leveled up a fair bit, and maybe had to place totems to raise raid level to get the enemies who will rape male MC.
