PVP = arena. Ignore it for the most part, you're too early to worry about it.

PvP and PvE stand for 'Player vs Player' and 'Player vs Enemy' - common terms in MMOs. In this game, though, there is no real PvP - even in the game modes where you are fighting a team of another player, it's the AI that is actively controlling their champions, not they themselves. But indeed, it refers to arena / tag team arena. 

However, the real distinction to make with your masteries is whether you want to make the champion a) stronger against bosses in dungeons, DT, Faction Wars, the Clan Boss, or b) stronger against waves of non-boss enemies (in arena or on the waves of dungeons, DT, FW). In the first case, that almost always means going for the Warmaster or Giantslayer masteries on the offense tree, as well as some other masteries which e.g. increase your damage against enemies with higher max HP than yours. In the second case, you'd go for other masteries, like the ones that give you bonus damage or bonus speed after each kill, heal you on each kill, etc. HH basically uses 'PvE' and 'PvP' as a short hand for those two approaches. 

At your level of progress, focus on the 'PvE masteries'. It's the dungeon bosses that are the problem for you now, and the Clan Boss of course. Those masteries will be less useful in arena, but they'll still help some. Besides arena, it's mostly only in the end-game that you really need the masteries focused on waves of enemies - for Faction Wars and Doom Tower especially. 

Thanks both!  That makes sense.  @kramaswam.kr - very consice, I always appreciate concise.

@L9753 - you are always helpful with detailed answered. I thought I was translating PvP and PvE correctly in my head but was confused because as you say, I'm not *really* against another player (in that another live player is against me in the arenas) but they are teams built by players.

Now I know where to concentrate my most used Champions for now and keep the other advice in mind for down the road.

By the way, congrats on Bad El Kazar, I don't remember if you mentioned before that you have him. He's amazing - yes, Ninja should still be your first 6* because he's more suited for campaign farming, but BEK is probably a better champion with more added value overall. And for your legendary books, give BEK priority, at least for his second skill cooldown reduction. 

Thanks for the tip, yeah, I got him a while ago....had to open 2 sacred shards to complete the task for another game but I really enjoy this one as well so I keep playing it.  I like all the strategy in it but I need a second device to really play it well - both my main games share a device and it can get cumbersome at times to try to be very active in both.

I have to disagree. HellHades does not use PvP as synonym for PvE wave content (and it is the right decision from him not to do so).

For example Thylessia: the option "nuker" is the same in PvP and PvE, but the option "debuffer" in PvE includes Warmaster as tier 6 masterie, while "dec def" PvP has Eagle Eye - for a good reason: Arena opponents usually have higher res than dungeon waves (in higher arena stages, you don't need Eagly Eye in bronze or silver).

There are more differences between these areas of the game. In general you can assume that your opponents in arena hit much harder, but have less hp than PvE enemies.

I won't claim to be an expert in HellHades' site, as I generally consult Ayumilove instead, but I've done some comparisons between the two in the past. Which is partially what my reply was based on: Ayumi shows two builds for most champions, one of them named 'Arena, Doom Tower, Faction Wars' and the other 'Campaign, Clan Boss, Dungeons'. And those two largely correspond to HH's 'PvP' and 'PvE' builds as far as I've seen. 

To go with your example, if the 'PvP' version has Eagle Eye, it's not only for high level arena that you'd need that, but also for the hard Doom Tower where you need much higher accuracy than normal. Of course, that goes for the DT bosses as well as the waves, on the bosses the Warmaster approach may still make more sense but as you'd be using the same champions on waves and bosses probably, might go for Eagle Eye for DT builds overall. Same way that for dungeons, you'd go with the Warmaster approach even if for the waves separately, you might prefer another path. 

Not sure if I can add to this thread or start a new one....looking for advice on who to work on next - I want another Champion ranked up during CvC if I can (ranked up Ninja this morning)

Bad Al-Kazar to 6 stars (may not make it during CvC)

High Khatun to 5 stars

Sandlashed Survivor to 5 stars (I've used this one less so her artifacts aren't upgraded as much and she isn't ascended as high as High Khatun).

BEK no question. He'll carry you through dungeons.

Awesome, thanks - I'll work on ranking up all the sacrifice champions and probably rank him up next CvC since I don't think I'll get enough 5 stars before end of this one.

At the level you're at, I wouldn't delay your next 6* by two weeks just to be able to do it during the next CvC, that doesn't make any sense. CvC points are nice, but not that nice that you should put your progress on pause inbetween. 

Thanks, I'll keep that in mind - I delayed this one only a couple of days.  I will see how long it takes to get enough for the next - I have a bunch more 3 star and 4 star sacrifices now than when I was trying to rank up Ninja so it may not take me to long!  I'm going to try to rank up as many sacrifices as I can during this CvC to get the points.  

I feel a bit bad because I'm not in a horribly competitive Clan but still the bottom of the active list (we have at least 10 people that scored no points in the last CvC) and I like to pull my weight.

I  think  you  should  go  with  Bad  El  Kazar  because he  is  number  1
