There are several proposals.
First of all, what will have to be bought for real money:
- Make the acceleration of building construction (for example, 2 times) - the cost of 3-5 dollars.
- Enter the promotion once a month / quarter with the purchase of 10 heroes with a 30-50% discount, but only for the money. This action should work immediately with the menu for the acquisition of heroes. Similarly you can consider and detachments 3 and 4 stars.
- Add in promotional sales for 600-1500 crystals of heroes 4 and / or 5 stars. Either by the principle of guaranteed to receive or receive at least 2 of …
- Add on the 20th level of the citadel portal of eternity / underworld / heroes (here for consideration or on a permanent basis or also activation for a month for 3-5 dollars). In this portal quests are activated - once in 2-3 days with a chance of falling out 3-4-5 star characters and rare things from 3 stars and higher necessary for the rebirth of the heroes.
- For 5-7 dollars per month: add another location (ghost / cloud / mystical) for four buildings: a) the market - allows you to change the resources of iron-meat for your own needs, the ratio of exchange to correlate with the level of the building; b) training camp for detachments; c) recruitment of recruits for the production of heroes and orders for iron / meat; d) training camp in which it is possible to get MAGIA trainers - for the possibility of 25-50-75-100% pumping magic - this is so that you can prove magic to the heroes who have the maximum level of pumping, but not magic. The pumped buildings do not disappear after the expiry of the term, but become inactive. When you re-activate the location, you can continue to use the buildings
Secondly, just cosmetic improvements:
- Reconsider the magic of the heroes in the part of adding to each color their individual unique features (fire-burning, nature-reduction / increase in damage, ice-reduction / increase in defense, order-decrease in accuracy, chaos-poison)
- Redraw the Hero Cards with a change in appearance when pumping and increasing ranks.
- Add rewards for 5-10-15-30 days of permanent entry
- Make rewards for the main tasks on the map
