When discussing Borderlands 2, the first thing usually mentioned is the builds, skill trees, weapons, shields, and even class mods. Normally, grenades don’t usually get so much attention from players or guides, and that’s why, when it’s time to equip grenades, there’s always a lot of confusion.
Today, we will discuss the best grenade mods in Borderlands 2 and where to get them. These will be the strongest grenades in the game (all legendary) and are usually used in one build or another.
#1: Fastball


First on the list is the Fastball, considered the best grenade in the game. Although you may have your preferences, it is almost undeniable to say that this grenade is a little ahead of the others, so this grenade should always be the first one you have equipped.
That being said, there are some builds that will tell you to bring a specific grenade mod. In those cases, you should use the recommended grenade over the Fastball.
Where do I get it?
If you have the game without updating, this grenade will be a random drop; it can only be dropped by enemies, in chests, etc. But if it is updated, the enemy that will drop it will be Boll.
To unlock this boss, we will have to do the secondary mission “in memory” that Lilith will give us in Sanctuary after the mission “On the hunt for the fire hawk.” At the end of the mission, we can farm Boll to obtain this powerful grenade.
Fastball Special Effect
The effect of this grenade is a reference to Baseball because a fastball is a way of throwing the ball in this sport. The effect of this grenade is that when you throw it, it goes almost without falling, completely straight, with only a few frames of lost height.
On the other hand, it should be noted that it does a LOT of damage: Fastball is the most damaging grenade in the game. However, it is not so easy to use it, since to kill an enemy, you have to give him a direct hit since the explosion radius is almost null. This makes you run out of grenades very quickly, but if you have good aim, the damage you can do is very high.
When should I use it?
As we said before, this grenade is excellent if you have good aim. You should always equip it as your first item. On the other hand, remember, it is still a grenade in Borderlands 2, so you should try to find a variation of this grenade with good utility. Therefore, the best thing to do is to farm it until you get a good version.
Although all characters can use it and take advantage of it, we particularly recommend it for Axton and Krieg.
#2: Rolling Thunder


The Rolling Thunder is another great grenade mod for Borderlands 2, but it never gets shown any love. Truthfully, it really isn’t the best grenade mod in the game (partially because you are liable to down yourself with it), but it is still rather strong.
Or maybe I’m just saying this to troll you. Who knows?
Where do I get it?
To get this grenade, you can farm it from Wilhelm who has a 5% chance to drop it.
If you have DLC there is a much easier way to get it: You can simply buy it from the vending machines in Torgue. It may take a while to appear, but I assure you that sooner or later, you will see it. It’s a 16% drop rate for a machine.
Special Effect
This grenade has the rubberized effect. This means that this is one of those grenades that bounces off the ground and walls until it finds a target, explodes and releases other smaller grenades that do less damage. Also, every time it bounces off the ground, it makes a small explosion that does more or less the damage of one of the smaller grenades. When it finishes bouncing, it leaves 8 to 10 small grenades on the ground.
When should I use it?
It depends on your taste; this grenade can be very good or very bad. Let’s start from the base: not everybody likes the rubberized effect. If you don’t understand how to use them and even consider them bad, we warn you in advance: This grenade is not for you.
With that out of the way, Rolling Thunder is a grenade usually underestimated by people who don’t see its potential. It is one of the few grenades perfect for starting a battle in the open field, as it can reach very far ranges and severely damage many enemies gathered in the same place.
On the other hand, you must know when and how to use it, so this grenade is very situational, and you should not have it equipped as a first option. For example, if you are cornered and decide to use this grenade, it will not save you, and as a punishment for using it at close range, it will probably kill you.
Pandemic


Where do I get it?
To get this grenade, you must kill the boss, Mortar. This boss is found in Sawtooth Cauldron, and we will face it as part of the main story. The good thing is that this boss is pretty easy to defeat, and you shouldn’t have any problems when you want to farm it.
The Pandemic has a 10% drop rate from Mortar.
You’ll want to get the longbow version of the Pandemic; otherwise, it isn’t a very good grenade mod, if I’m being honest.
Special effect
Spawns a corrosive cloud upon detonation, then spawns three more homing grenades. The grenades spawned will chase enemies, transferring corrosive damage on contact and then seek out another target. This will continue until the grenades disappear.
When do I use it?
This grenade is useful in exact moments since, appearing only in corrosion, it is very good in an area where many enemies are weak against this effect, for example, Hyperion’s robots. Against other enemies, it is still strong, but you won’t be able to use it to its full potential. For those cases, use the Fastball.
This was our list of some of the best grenade mods in Borderlands 2. Do you disagree (probably)? Then leave a comment below and tell me about your experience with the Rolling Thunder!
