Event Bonus CEs

! Important ! Steps 75 to 85 (in other words half of Day 6) unlock on the 21:00 PDT, which is basically another day. It would be great if Steps 75 to 85 were put into a "Day 7" section with the exception of step 78 (the quest "The Actress is Gone/ The Actors Are All Gone"), which unlocks after step 74.
Thanks so much, I've made an additional Day 7 section with Sections 16 and onward (and kept "The Actors Are All Gone" in the Day 6 section since it can be cleared ahead of time). It should reflect in a few minutes; make sure to refresh!
Can't access section 16 until next reset. Seems there is an entire extra day of waiting
Thanks, I've moved 16 and onward into a new Day 7 section!
Thanks for your hot spicy guide!
The lvl 90 free quest (called “Actress” here and “The actors are all gone” ingame) is primarily a gold currency quest with a secondary bronze currency and NO silver. The guide lists it as being primarily all three currencies.
Thanks a bunch! CE listings were correct but the currencies were wrong. I've fixed both mentions of the Lv90 quest (in Step 75 and Step 95 after reorganizing them for Day 7). Should be updated in a few minutes!
Just a heads up, step 27 only has 1 checkbox while you are recommending doing it 3 times. Other steps that require multiple clears have multiple checkboxes, so it would be neat if thw3 author would change that.
Done, thank you so much for the catch!
Step 59 is not a "NPC Solo" quest, but a "Mandatory Setanta" quest, like the quests in step 87, 90 and 92.
Thanks, updated both! Should reflect in a few minutes.
Step 51 is also in the same boat- Mandatory Setanta Frontline but also NPC Support Mandatory
Step 65 (Free - Mage Lv80) should be primary silver, secondary gold.
Oh you might actually have done the Okeanos node (Free - Storm Lv85) instead of the London node (Free - Mage Lv80), since the Okeanos node is the silver currency node. I almost did this too since the last Main Quest you do ends on Okeanos, I'll add a note that says this should be on London and not Okeanos.
Maybe late to the party, but on step 21, Chapter 4-1, 4-4-4 layout is kinda incorrect because they will summon another one if you didn't kill them all, so if you kill them all at once you only need to deal with normal 3-3-3 layout
Thanks a ton! Updated step 21 to reflect this.
