Is Alter Self Good in 5e?
Alter Self is a good choice for characters who need to adapt to various situations and challenges.
However, the spell’s usefulness may vary depending on the specific situation and the player’s preferences and character.
Advantages – Alter Self
No Material Component
Casting Alter Self without the need to carry or prepare Material components makes it more accessible whenever you need it most.
Its benefit is specifically shown in the middle of combat or other high-pressure situations where your access to materials may be limited.
Extended Duration (Up to 1 hour)
There are various ways in which an extended duration can be helpful.
It can allow the caster to have a longer period of time to utilize the abilities and resistances.
Let the caster stay in their altered form for longer and avoid the need to constantly recast the spell.
A long duration can also increase its versatility and usefulness for the caster. Making it a good option for offensive or control mages.
Disadvantages – Alter Self
Concentration spells require you to focus on the spell’s effects, which can be difficult in combat or stressful situations.
Note: It is especially dire when your Concentration is broken in the middle of a fight, as it can leave you vulnerable.
You can only maintain one Concentration spell at a time, so choosing Alter Self could prevent you from using other, more useful Concentration spells.

When or How Should I Use Alter Self?
Alter Self can be used to infiltrate an organization or location by appearing as someone who is allowed entry.
Note: Remember to keep your Concentration up, as failing to do so will cancel the transformation.
However, using the ‘Change Appearance’ option only changes your appearance and doesn’t grant any abilities or traits of the chosen form.
If combat lasts for quite a while, you might run out of high-level spell slots or not have close-range spells.
If this happens, simply use Alter Self and join the fighters!
You’ll be more proficient in unarmed striking, meaning you don’t require a weapon and can be useful without casting spells.
