Upgrade from lvls 1 to 5 (inclusive)

Important to note that other classes have 3 hexa stats (>10% FD total), which is absorbed into our shinestones.

The first sadalsuud boost stone (there are two)

The % FD gained per 100 frags spent.

100 frags is a rounded up figure for the average cost of each upgrade in our hexa board,

For skill stones that are split into 2:

i.e., this efficiency gives a sense for the rate of FD% gained per enhancement in our board

These cost ~1k less frags than the regular hexa system due to being able to split levels

The location of the rush stone with respect to our hexa tree

Our progression is quite front loaded with a lot of gains made by upgrading only a few skills

For skill stones that are split into 2, there are the individual levels of each stone

For example, just unlocking M1 and M2 gives us ~37%FD for 300 frags.

The level of Salad (1) and Salad (2) sum to give the total effective level

This is the expected frag cost in the case of shinestones, which are RNG

FD gains from stats partially account for its multiplicative effective with skill damage (see technical notes)

Excludes cost for things like janus and drop rate/exp rush stones

- This ordering is fragment-oriented, for those that are erda/meso gated, the ordering will change. Feel free to use the efficiency scores in each tab as a guide

Quite a few niche stones are not accounted for here, see 'Technical Notes' for some details

- The frag cost is the EXPECTED (average) cost in the case of shinestones

- This ordering accounts for stones that need to be unlocked before further stones can be upgraded.

- Some assumptions are made, these are labelled on the right.

(Mains) Grab sol janus to get M1 Ray into light zone.

35% boss/dmg/abnormal dmg

(Mules) Ignore sol janus and grab 2% normal dmg (L) instead.

In total, 225 (mains) or 150 (mules) frags needed to unlock M1

4% crit damage

Note: Cumulative cost column does not include Janus cost!

Any of the 1% IED stones in the three vertical line will do

In total, 150 frags needed to unlock M2 (after M1)

20% buff duation

10% summon duration

14% normal damage

30% exp every 30s for every 250 combo kills

Get shine to whatever level is required for you to consistently cast vega + seashell inside shine buff

0.5% chance to reduce skill's remaining cooldown by 20%

You can also grab some of the DOWN rush stone stats towards shine (2) and then

10 sacred power

alternate levels between shine (1) and (2), the efficiency is just a little worse is all

Shine is a strange boost; the duration only increases every 2 levels

This is a fairly deep investment to reap the FD gains, feel free to delay upgrading shine

Additionally, you can also delay upgrading shine if you're happy to learn Sia combos

Two skill stones are unlocked by now so that Shinestone #2 can be upgraded.

This could be any combination of Janus, Shine, or Salad.

For mules, unlock salad (below) first before going for these shinestones!

Two boost stones are needed to unlock shinestone #3 in the next goal

Left utility rush stones (such as EXP and drop rate) OR Second Hexa Shine skill stone has been unlocked so that light zone reaches m.atk boost stone

If you do not want these stones, you can skip getting the m.atk boost stone for a while

Although it is 'optimal' to upgrade these shinestones ahead of the previous goal,

the liklihood that you start to downgrade becomes noticeable at lvl 13 and above

If you don't mind the risk, go for this before the previous goal

Total sadalsuud level is 10. Equivalently, you can get stone (1) to 6 and stone (2) to 4.

As before, although optimal to get this earlier, I've delayed any shinestones at or above lvl 13
