Guild Wars 2

Are there any builds for open world scrapper / engi? I am trying to get my mastery levels and is there any optimizing build to level up fast?

Also can you recommend me which food buffs / utility buffs i should buy for more %xp or anything else to get the mastery levels faster? Are there any maps/places that i can farm much faster mastery levels with?

Thanks

If you read through this sub forum, you may find several pve-builds which work pretty good. For example:

about mastery farming:
- halloween food for a straight bonus of + 25 % exp on kills

(+ 48 % magic find as a bonus)
- get an exp booster and head for organized maps with large events with many mobs at once. Once the killstreak is charged to maximum, your exp loot is extreme.
- if you are in a guild with a guild hall, visit the tavern and get the Guild XP Gain (lasts 24 hours and costs 0, increase depends on the guildhall status)
- if you are on a map with a big event about to start and you have a weapon which tags lots of monsters (e. g. the flamethrower), you can also consume some fireworks a few seconds before it starts. This gives you another + 10 % experience from kills.

- in addition, if you farm only with that character and already own an ascended necklace, you can purchase an enrichment infusion for experience gain at the laurel vendor (10 laurels) to boost your exp by another + 20% from kills.

about maps, well it depends if you want tyria experience or heart of thorns experience. Bloodstone Fen is mostly designed to farm loads of experience, you can buy a permanent map-buff which increases your exp on that map by 10 % (up to 3 tiers). Also there are blue orbs flying in the air which you just have to touch and they give you a fixed ammount of exp. The ember bay is also an option, but that map is mostly to farm karma. Also good sources are the meta events in VB, AB, TD and DS. Look for organized squads in the lfg.

For central tyria experience it is not that easy. Orr is still a thing, temple events. Silverwastes can be a little gamble atm. Also you may want to visit old, lowlevel maps. Especially when the daily events are on those maps. But you can also go for regular low level maps. The thing is this:

We do get downscaled on those maps to the appropriate level, but only a little. Most of our power remains untouched, what makes us somewhat overpowered. When you go for the right gear you can nearly 1shot enemies at ease. If you go into lowlevel maps, you aim for yellow mobs and travel away from the traditional routes. Places where nearly no events take place, far away from waypoints or just unfriendly territory. You get bonus damage in this game for monsters which live long untouched. The longer a monster survived, the more bonus exp it gives. If you use the consumables I mentioned above, even without the killstreak booster, you may gain extreme ammounts of experience within a few minutes.

I leveled my masteries mostly in the old hot maps, before the qol change and in tyria in lowlevel maps (with the above described method). I used a few exp boosters, lots of food and no enrichment infusion/fireworks. Did not even use the cof exploit and still felt it happened way too fast.
