If you really want to tower, you need to suck up to leads no doubt about it at least be friendly to them. If one of them hates you, you're screwed, just go to a different towering guild. Try to join early, like around 300h-ish and make sure that the people in it have experience with towering.. or else it will either take extremely long to 1k or it'll completely fail.

I mean, or you could be online for 12 hours a day and then you might be noticed above the 200 other people that randomly help the guild.

Towering is probably not for you if you don't enjoy staying at one place for hours on end without going afk.

For pk, you can join a pk guild or just go on any tag and just pk. Popular places are at towers (mostly MoD and Sards). Other places have long distances to the flag room where you'll get most of your kills (or the halls in Sards). If you just want stats tho... honestly just go spam your sword for a few hours in a mob/crowd (usually can be found in front of daycare centre or in swamp near giant blob spawning area).

For spar, well GL this is probably the hardest aspect of the game (imo). I can't spar so can't really help you there, but you'll probably want to do a lot of practice spars against good sparrers and you will improve. Again I have absolutely no skill here. Just beware of toxic players!!

Alright, now for graphics its more laid back, I would recommend visiting the graphics subforum and just looking through other people's work and trying to get a grasp on pixel art. Try making some stuff, make a thread there, and people will gladly give you cc (constructive criticism) to help you improve! You can make heads bodies whatever really you feel like, doesn't even need to be graal related.

Mostly just try and have fun, but remember if you are going to tower, it will probably take a lot of time away from other aspects of the game (ie. if they see you online but doing pyrat quest, you're probably not going to be praised). But, you can get away with a lot if you've got them connections.
