What Top Mortar is
Top Mortar has a projectile-firing active ability. Hotfix 0.9.6 reduced the number of projectiles fired by that action. For a returning player, the active sequence is therefore the part to revisit when comparing current play with a launch-era demonstration.
The module’s name and the appearance of an attack are useful starting points, but the practical choice is how its current action fits the encounter. Look at what it contributes when you use it, not only how many projectiles a clip appears to show.
How to plan an activation
Guide advice: bring the fortress into a readable situation, identify the opportunity you want to use, and activate with enough attention left for the next movement decision. Notice whether the action helped with the intended threat.
A crowded scene can look effective while leaving the immediate dangerous target unresolved. Separate pressure across a scene from the contribution that matters to your next move. This helps you decide whether the action fits ordinary encounters or a particular major-fight opening.
When to choose it
Consider Top Mortar when exploring projectile-based active offense. It is useful to compare when you are comfortable with your vehicle and want to change the offensive action around which you plan an approach.
If you already struggle to use available abilities on purpose, practice the existing routine first. A new projectile action should not become another distraction while the castle drifts into danger. Learn the sequence in manageable encounters before building the entire run around it.
Strengths and tradeoffs
A projectile-firing active action gives you a deliberate offensive option to evaluate during openings. It can be the focus of a build experiment in timing and positioning, especially when you want to move away from a contact-oriented routine.
The practical cost is relying on how the attack looks rather than what it accomplishes. Several visible projectiles do not tell you whether the action solved the current threat. Evaluate readiness, application, and the position left after using it together.
Build choices and comparisons
Fire Mage offers Firestorm as another offensive action to explore. Side Ballista and Front Barracks are useful comparisons for active-oriented play. The question is which action fits the openings you create, not which module has the most impressive single screenshot.
Huntress’s cooldown drawback matters when an active action becomes central to the plan. Force Mage is a separate consideration when the problem comes from incoming projectiles rather than applying your own attack. Keep offensive experimentation and defensive needs visible as separate decisions.
Beginner tips and common mistakes
Start by using the action at an opportunity you can clearly describe. Afterward, ask whether you improved the situation and whether your next route remained comfortable. Make one change to that sequence if it did not work.
Avoid assuming that ordinary enemy-clear footage establishes performance in every major encounter. Also avoid using an old projectile count as your expectation after 0.9.6. Try the current action in your own familiar setup before deciding how much of the build should depend on it.
