So rough estimates....

7 Sacreds, 30M silver, 1000 gems.  

Shards are always the most crucial but if youre doing UNM everyday you get plenty in-between fusions to do them all if you choose.

Since you are late game already, you can easily complete fusions with the resources the game provides.  

For many players, it does require a shift in play-style:  Shards, Soulstones & Gems are resources that must be saved and managed in order to facilitate the compeltion of Fusions, Titan Events & Path Events.

If you can't embrace that Deferal of Gratification, you won't be able to complete fusions and other events as a F2P player. 

Hydrid Fusions are the toughest; Traditional are the mid-ground; Frag collectors are the easiest. The fusion that starts next week is a frag collector, so that is the best time to get your feet wet....assuming you have some Sacreds in the bank.

I am doing this Summon Rush the grindy way because I do not want to pull Sacreds.  I have every one of the non-void burners that are on boost, and I came out of the Leo Path Event 12 into Mercy, so I really don't want to burn my Mercy on this.  

I had a lot of campaign to catch up on for my Monthly 500, so I am doing about 400 campaign battles to earn Diver Points and Mystery Shards.

I'll grab the first 5 Kroz Frags for 850 Greens and a 10-Pack of Voids.  I already have Venus & Sulfuryion, so I'll probably boost Supreme Galek.  

Anyway, this ramble was to demonstrate how to do an SR on the cheap.

I went a bit more expensive but 3 Sacreds + 4 Voids isnt a terrible ROI. 

@DarkM00se 

Were you able to complete the Kroz fragment event?  If so, you now have a feel for the resources required.  

A frag collector like Kroz is the easiest type of fusion.  The Yukimasa fusion starting on Monday will be a traditional fusion, which is the middle ground in terms of time/resources required.  Yukimasa definitely looks like a fusion worth doing.        

100%.  Very good for both PvE and PvP.  

some days after i made this post i managed to get into Gold 1 by farming turtle teams after realising bombs are the way to go, and pulling a 6 star soul Gaius.

All my prep i learned on this post forgotten lol.

Ive come back to reread after i failed to save for Hilvi

have they told us what type the march fusion will be?

i

i think ive prepped close to enough. more energy though. and i do know im low on gems.

Will it be traditional? also whats the difference

Traditional = you get rares, fuse to epic, then fuse those to get the champ.

Fragment = you get fragments for epics, use those to fuse the champ.

Iirc they also sometimes do fragments for rares to fuse into the epics, though they haven't done that for a while, from my memory.

Fragment is typically easier since you don't need to level the rares, though you also have fewer chances to skip events by pulling the champs instead.

Kram is off a bit:

Hybrid: Most Resource Intensive.  Complete Events to collect fragments for 4 Epics. Level the Epics to L50 and then fuse to the Lego.  Time-Limited. Must Fuse by the deadline in the Portal.    

Traditional: Mid Tier on Resources. Complete Events to collect 16 Rares. Level to L40, Ascend and then Fuse 4 Epics. Level the 4 Epics to L50, Ascend and then fuse the Lego. (This is the same type of Fusion as Rhazin). Time-Limited. Must Fuse by the deadline in the Portal. 

Fragment Collector: Easiest Type of Fusion. Can be completed relatively easily by daily players.  Complete Events to collect 100 Lego fragments. As long as you get 100 fragments, you can summon a Frag Collector anyiem you want.  They are often saved for points in other events like Champ Chase and CVC.

I am fairly certain that the next Fusion will be traditional.

Did you do Noldua?  She was a Frag Collector.    

Thanks.

no never did a fusion. This argonite is the first im going for. Mostly for fire knight. Im tired of the rng im getting from my ally attack freeze team for FK hard so im confident in finishing this new fusion. the energy is what im worried about. sitting at 2k and 300 gems im still not sure it s enough for the dungeons.

traditional could definitely work. 

Generally speaking you can finish fusions with just the daily rewards of energy as long as youre smart with it.  Just make sure youre collecting all the rares and its also worthwhile to plan out your actions using the calendar.  I.E. look to see when you can double or triple dip doing a dungeon with a solo champ to also work on champ training and gear diver.
