You have become severely afraid of spiders, to the point the very mention of them strikes fear in your heart.

• Whenever an abnormal spider (i.e. non-tiny) presents itself, you have to make a wisdom saving throw (DC by Size Below). If you fail, you are paralyzed until the start of your next turn.
• If there is an abnormal spider in sight, you have to make checks/attacks with disadvantage, as your attention wouldn't wholly be on the task.

To reflect your fear and paranoia of spiders, you gain the following benefits.

• You gain a +5 bonus to initiative when dealing with arachnid or similar, from your paranoia and fear always on the lookout for them.
• You gain a +2 to perception checks using hearing/seeing to detect arachnids or similar, due to your eyes catching the slightest movement and ears trained to their sounds.

FLAW. This is a flaw feat.
