Introduction:
Grimm’s Crossing, the new 3v3 map for Heroes of Newerth, is all about action and quickly asserting your dominance over your opponents. Grimm’s is a Match Making map, so learning and mastering it will lead to great rewards. This guide will give you a strategic leg-up over your peers and provide insight into some of the smaller nuances of Grimm’s Crossing. The guide will be delivered in three segments: the first will focus on which heroes the map favors, the second will detail successful play behavior on Grimm’s, and the third will go in-depth about important minutiae such as ward placement and map-specific tricks.
Part I: Favored Heroes:
Grimm’s Crossing, with its small size and focus on action from start to finish, naturally 
favors certain types of heroes over others. Hard carry late-game heroes won’t have the alone-time or the time at all to sit and farm their core items, while early-game nukers and disablers will see their effectiveness magnified and prolonged. This section of the guide will aim to highlight the heroes that excel on this map, as well as single out some of those that would be better left on Forests of Caldavar.
Top Tier:
- Valkyrie
- Bubbles
- Pollywog Priest
- Hellbringer
- Doctor Repulsor
- Defiler
- Witch Slayer
- Swiftblade
- Pharaoh
A couple of common themes have landed the heroes above in the Grimm’s Crossing top tier list. Pushing is extremely effective because the map is small and has only two lanes and one outer tower per lane. As a result, Pollywog, Defiler, and Hellbringer are some of the most appealing options out there. On a small map Mobility is more powerful than on Forests of Caldavar which means that some of the most effective mobile heroes in the game reign supreme on Grimm’s - think Valkyrie, Bubbles, Pharaoh, and Doctor Repulsor. Witch Slayer earns his spot with his impressive arsenal of disables and spike damage, while Swiftblade utilizes the map’s many tree paths to ensure that surprise is always on the agenda.
