Elemental Synergy tasks

The 1,000 Hero Soul Stones are a lot for only 15 Ancient Titan Artifact Chests 10 Lucky Coins.
Save your Soul Crystals for a better event, but if you can complete it with dolls and such it's a nice bonus.

You also need 50 Titan Artifact Spheres for this event, the 15 Ancient Titan Artifact Chests are worth it.
For another 950 Titan Artifact Spheres you can earn 22 Lucky Coins. If you have too many Spheres and pick up 3 Lucky Coins elsewhere bad luck protection will guarantee you'll get at least one Super Reward.

The Lucky Road is another gacha-style event. Don't invest heavily into obtaining the Lucky Coins to try and gamble for big rewards. Just be satisfied with the few coins you obtain by playing regularly and try your luck with those. That way any rewards you obtain will just be an added bonus without extra costs. The Lucky Coins can no longer be saved and used in a later event. At the end of the event they'll be automatically exchanged for Titan’s Tesseract of Luck.

This is where and when you spend your Titan Skin Stones (and also buy more). Essence of the Elements are also a good buy because of the sheer number you need with the cap increase to level 130. The third choice would be the Artifact Seal Chests, because you can't regularly buy them so they can be hard to obtain.

You also need 200 Summoning Spheres for this event, the 1,170 Points are worth it.
Combined with the 120 Points for 'Log in' you'll have at least 40,600 Emerald Coins to spend.

You need 200 Summoning Spheres for this event. 

All the other tasks are hard to complete. They either need huge amounts of resources, under-developed titans, or both. But with each element getting a new Summoner titan, things start to look a bit better. It might be a good idea to start saving resources for when we get a fresh level-1 titan. It still won’t be cheap or easy to get a good score in the Tournament of Titan Power, but at least it will be a little more doable.
