I used 1,000 greenies and then 60 blues to finish.  I got Vogoth twice so he is almost fully empowered.  

I save reds for 2x even if it never works out for me.   Love my greenies.  They are free points.  lol

Does this fusion seem easier than we expected?

Seems pretty standard for a mixed fusion to me.

I do event dungeon 20 with lydia, horsey and cheshire cat. Roughly 10 turn, 10 second runs with 2 chickens

If you want a Duo, Kro'Khad & Shy'ek are the fastest I have found. Marius & Freyja are my next best.

Both have been 100% win rate on L20.  

The Hero Path was easy for me and saved me 2 time consuming events/tournies.  

Helped me skip both Chase and Summon Rush which was nice.

Skipped Summon Rush and won't bother to finish the second DD over here.   

Can't blame you there. Renamed Dungeon Divers and Champ Training events are my least favorite things to do these days.

I skipped 2nd DD and Dragon.  I wanted to do Champ Train because I have a huge surplus of gems, 50% XP bonus and champs that needed to come out of the vault.  

I like to do Champ Chase when it falls on the last weekend of a Fusion because I fuse all the epics and typically the Lego on the way to the first Lego Book. You get half the points for "free".
