Upgrade Element

Objective: Upgrade the level of the selected element by one level

info

The Element Upgrade mission becomes available right from the first epoch, presenting an opportunity for heroes of any element to enhance their powers. This common-rarity task requires gold and the elementals of the corresponding type as essential components, challenging heroes to harness their resources and rise to greater heights.

Mission prerequisites

You can use this mission in any epoch starting from the first one. Any hero can complete the mission, regardless of the element they are dedicated to.

Ingredients

You need gold and elementals to complete the mission. Keep in mind that you need elementals of the same element as the tower you are upgrading. A specific amount of gold and elementals is required for each level of element upgrade. You can find the exact requirements in the table below.

level	Gold	Elementals
1	50	50
2	100	100
3	150	150
4	200	200
5	250	250
6	300	300
7	350	350
8	400	400
9	450	450
10	500	500

With each level, the upgrade process requires more time — see the table below.

However, the completion time also depends on the hero’s Mastery skills, which can significantly reduce duration of the upgrade.

Results

If there are enough ingredients and the mission is successfully completed, the selected element in the land will be upgraded by one level, providing additional gold income every day.

Each element upgrade by one level provides an additional 10 gold coins per day.

The elemental level plays a significant role in later epochs, determining the land’s level in general and limiting the level of buildings that can be constructed on the land.

Additionally, you will receive one medal for completing the element upgrade mission.
