Here you will find Techs that help you out in several ways in terms of teaming up with your alliance. Some of them are PvP focused while others are geared towards helping each other grow! Take a good look and see what sounds appealing to you and put a little time and gold here when you can. Most of these Techs can wait awhile and don't fall high on the priority list.
Alliance Help Amount:
Costing almost nothing and only 30 seconds per upgrade, might as well grab these 10 extra alliance help times.
Reinforcing Troop HP, Reinforcing Troop Attack, Reinforcing Troop Defense (each troop type):
Want to score some easy points in SvS? Get this maxed out so that you can lay traps effectively and do some real damage behind the scenes by reinforcing your alliance mates. Nothing better than a free +30% to all troop stats. Focus the Troop Types you're most likely to use when reinforcing first, primarily Archers, Siege, and Ground. Cavs can wait awhile until Ground Marches become a more common occurrence in your SvSs.
Super Reinforcing HP, Advanced Reinforcing Defense, and Advanced Reinforcing Attack:
These more expensive and time consuming Techs will add a large amount to the buffs of ALL Troop Types when reinforcing so make sure to keep them upgraded as well if you plan to help out in this way.
Reinforcing Capacity, Super Reinforcing Capacity, Rallying Capacity, and Super Rallying Capacity:
Pretty sell explanatory, grab some extra space in your rallies or in your embassy. Super essential for late game PvP as you will need all the room you can get.
Reinforcing March Speed:
Get to your buddy faster and use less March Speed Ups.
Transportation (all resource types):
Increases the amount of resources you can transport in one go. Not a big deal unless you are shuffling around a bunch of resources from alts.
Alliance Agriculture, Lumbering, Masonry, Mining (and their Super Versions):
Speed up your gathering when at the Alliance Resource Tile. This helps you gather more, faster. That's about it.
Alliance Agriculture, Lumbering, Masonry, and Mining Bonus:
Like Jindoek, these Techs give you a bonus amount of resources at the end of your gathering, but only apply when gathering from the Alliance Tile.
