Arena / Adrenaline questions

Is the arena for low-level characters only? That's what I was told. In that case, what is the maximum level? How important is the tactics skill in the arena?

What do the numbers for an adrenaline-based skill mean? For example, a "2" surrounded by red lines next to a 4. I assume the 2 refers to the level of adrenaline. Is the 4 the number of seconds it takes to reach 2 adrenaline? Does it tell me anywhere how much adrenaline I have?

There is an arena for levels 1-10 in ascalon, shing jea monastary, and kamadan, and for prophecies, I beleive a 1-15 arena somewhere around yaks bend.

Im guessing the 4 you are talking about is a cooldown, you have to wait 4 seconds to begin gaining adrenaline for that skill again. The 2 is the level of adrenaline needed. When you leave town, that skill will be darker, and as you make each attack, you will notice a fire start coming up, for each hit, you gain 1 adrenaline, and finally, when the skill is ready, it will light up like other non-adrenaline based skills.

srry, posted what rothaga said x.x srry. anyways, he has it correct. I'l add this- low level arenas are mostly played in AA(ascalon arenas and SA(shiverpeak arenas).

Yes Ascalon has an arena for characters lvl 1-10, up to 15 at Yaks Bend. This is kinda an intro to pvp arenas.

When I was warrior way back when, I found the Ascalon arena pretty pointless since many people try to get runs to Droknars Forge, and get max armor and weapons and play in a low level arena. I guess some people get kicks out of that, I never understood that.

Anyways, try them out, have fun in it, expect to die badly a few times, but dont get discouraged.
