7 xp days elixir + adventurer 15% permanent kits...stack?

[Morholt]

7 Day: +50% (50% bonus)
Combo: +60% (110% bonus)
Adventure pack: +15% (125% bonus)
Abaddon: +10% (135% bonus)
Arlorian Eggshell proc: +10% (145% bonus)

So if you gain 1,000 xp normally, you could gain 2,450 xp with all of these elixirs



During a double xp event: +100% (245% bonus)

During an occasional double xp event and stacking all the above elixirs, if you normally gain 1,000 xp doing something, you would instead gain 3,450 xp

If I'm not mistaken, I believe double xp event HAPPENS before anything else. Mobs simply grant twice as much.
THEN bonus xp percentages come in. I do believe you get 3 xp per normal 1 xp kill during the double event and using a 50% bonus elixir. Anyone remember checking recently and able to confirm this?

So the theorethical max would be double xp event plus the +145% bonus xp. Which would be a massive 4.9 times normal xp.
