Attack on Titan : Tactics Unit Roles and Titan Mechanics

Attack on titan: Tactics tower defense gameplay is comprised of various titans each with their own attack patterns that are able to be countered when the appropriate unit is deployed. These titan types are outlined below:

• Running: Ignores units and heads straight to wall. Low HP
• Downward-looking: Only targets units that are the ground. Medium HP 

• Roaming: Targets any unit on the field, deadly in groups. Low HP

  
• Starving: Incapacitates ground soldiers and ODM troops that have landed. High HP 
• Striking: Charge up attacks that will deal considerable damage but are weak to arm cutters. High HP
• Swiping: Can attack multiple ODM units at once and interrupt attacks. Medium HP
• Trampling: Leaps towards weapons and ground troops. High HP 
• Upward-looking: No interest in ground based units such as traps and cannons. Medium HP
• Fast Abnormal: Ignores units and heads straight to base, weak to leg cutters. High HP 
• Grabbing: Incapacitates airborne ODM units. 

It is therefore important to ensure your team is well equipped for the stage that you are attempting. This is especially crucial in recent events as there has been generally an increase in difficulty making stage farming less efficient and time-based objectives harder to achieve. 

Characters roles in AoT Tactics have strong strategic value when completing end-game content or aiming to complete a stage as efficiently as possible. Some units excel in their roles while others are outclassed and some roles may be less important than others which is aimed to be portrayed within the tier lists.

1. The most important factor when building your team is proficiency as without meeting stage requirements your units will be significantly weakened. To achieve this make sure to do Chapter 8 Hard Mode daily to receive the necessary proficiency materials to reach gear 40. 
2. The second factor to consider is whether a unit has type advantage on the stage. Units with type advantage will be provided with noticeable stat buffs that stack with any other existing buffs such as leader skills and SP boosters. This means units with type advantage generally will outclass all non-type advantages units in their role so it would be wise to train a diverse line up of units. 
3. Lastly you must consider the titans on the stage and bring suitable units that are able to efficiently clear the stage. This can be achieved by the varying roles of each unit by considering their strengths and weaknesses.

ODM AOE Units:

ODM Damage dealer (Low Hit Count):

Long-range and short-range restraint traps: Specially designed utility that are able to trap titans for a short period of time preventing them from attacking and moving. Long-range is most suitable against groups of titans while short-range are mainly used to trap bosses and cheap card cycling. Not very effective when titans are spread out or are swarming the field. (More suitable for AoE damage SP) 

Nuker SP: Characters that deal huge amounts of damage with their SP to a single titan on the field. These are most commonly found amongst 3 and 4 star units such as training corps eren, ymir or christa. These are especially crucial when facing bosses with large amounts of HP that need to be dealt with quickly such as the recently released armored titan event. 

AoE SP: 

Sub Roles

Titan Shifter: The ability to shape shift into a titan that will attack any nearby titans and rescue any grabbed units after a full combo (Currently only Eren). These shifters have very high HP ranging from 100-300k making them excellent tanks for your ODM units while also dishing out some nice damage. 

Stun: Characters with the chance to immobilize titans for a short period of time after each hit. Most effective against swiping or fast abnormal titans as it will always activate but not very effective against other titans as it has a very low success rate normally. 

Barrage: Characters with increasing damage multipliers after each hit coupled with high hit counts. Most suitable against titans that ignore airborne units but heavily disadvantaged against grabbing, swiping and striking titans.

Healing SP: Units that are able to revive and restore units HP that are on the field. Most useful while lots of ODM units are on the field and are close to death. 

ATK Boosting SP: Units that are able to deal significant amount of damage depending on the number of units on the field. Best used against High HP titans and bosses that need to be defeated quickly. However they are generally not as useful while their SP is not active. 

Leader skills: These are comprised of 4 varying buffs: ATK, HP, SP Start gauge and SP charge rate boost. The most suitable will vary on the layout of the stage and how many members of the team are affected.

- ATK leader skills will be favourable against High HP Titans and shorter stages that need to be cleared quickly.

- HP leader skills are the least useful of the 4 but can make for some fun teams when combined with healers and titan shifters. 

- SP Start gauge leader skills are useful against shorter stages with only 1 wave 

- SP Charge rate boost leader skills are best used in longer stages where SP skills are needed throughout the battle.
