This build is good if your team doesn't have a strong healer, and it works very well with a Tassadar. While going to save you a lot of health, Falstad is still vulnerable to ganks, silences, and especially blinds, as you cannot heal yourself if you cannot hit your enemies. This build offers probably the highest available damage potential (and self sustain) from any Falstad build. If the enemy doesn't have multiple high health heroes you can replace Giant Killer (level 13) with Flow Rider to improve Secret Weapon uptime. At level 20 Nexus Frenzy provides you extra range and attack speed, both of which will improve your damage output and thus your healing by a large amount, but Epic Mount can be a worthy replacement on larger maps.

The Ben Franklin Build is a situational one that works well against ranged heroes with a considerable amount of poke damage. Note that this build really only shines on maps with Siege Giant camps, as these will provide you with the easiest damage upgrade for Lightning Rod. Static Shields at level 4 give you a decent amount of shields that should help in mitigating a lot of damage during fights, just make sure you cast Lightning Rod on less mobile heroes - this will become less of a need with Charged Up at level 7, which allows you to engage from safer distances and provides more shields. Either heroics can be picked, but I prefer the damage increase over the utility in this build as it's damage output is not as good as the Basic Attack Build's. As an added bonus this build has the best available mobility for Falstad.
